主要原著論文
1. Cheng Liu, Changhong Hu, An actuator line - immersed boundary method for simulation of multiple tidal turbines, Renewable Energy, 10.1016/j.renene.2019.01.019, 136, 473-490, 2019.06, [URL], This work proposes an efficient actuator line – immersed boundary (AL-IB) method to predict the wake of multiple horizontal-axis tidal turbines (HATTs). A sharp IB method with a simple adaptive mesh refinement strategy is used to improve the computational efficiency. The velocity and other scalar fields adjacent to the solid surface are reconstructed by a moving least square (MLS) interpolation. A computationally efficient AL model is applied to represent the rotors by adding source term to the governing equation rather than resolving the fully geometry of the blade. To predict the turbulent wake, the AL-IB method is implemented with an unsteady Reynolds-averaged Navier–Stokes (URANS) solver. Performance of three types of turbulence models, k−ω−SST model, standard and corrected k−ω model are evaluated. An efficient wall function model is proposed for the MLS-IB approach. The accuracy of the present AL-IB method is validated by numerical tests of a single rotor and multiple tandem arranged IFREMER rotors [1,2]. Wake interference of Manchester rotors [3] with side by side arrangement is also investigated numerically. The predicted wake velocity and turbulence intensity (TI) are in reasonably good agreement with the experimental results..
2. Cheng Liu, Changhong Hu, Block-based adaptive mesh refinement for fluid–structure interactions in incompressible flows, Computer Physics Communications, 10.1016/j.cpc.2018.05.015, 232, 104-123, 2018.11, [URL], In this study, an immersed boundary (IB) approach on the basis of moving least squares (MLS) interpolation is proposed for analyzing the dynamic response of a rigid body immersed in incompressible flows. An improved mapping strategy is proposed for a quick update of the signed distance field. A CIP-CSL (constraint interpolation profile - semi-Lagrangian) scheme with a compact stencil is adopted for the convective term in momentum equation. Fluid–structure interaction problems can be solved by either the weak or the strong coupling schemes according to the density ratio of the solid and fluid. This research is based on our previous studies on block-structured adaptive mesh refinement (AMR) method for incompressible flows (Liu & Hu, 2018). Present AMR-FSI solver is proved to be accurate and robust in predicting dynamics of VIV (vortex induced vibration) problems. The efficiency of the adaptive method is demonstrated by the 2D simulation of a freely falling plate with the comparison to other numerical methods. Finally, the freely falling and rising 3D sphere are computed and compared with corresponding experimental measurement..
3. Changhong Hu, Cheng Liu, Simulation of violent free surface flow by AMR method, Journal of Hydrodynamics, 10.1007/s42241-018-0043-4, 30, 3, 384-389, 2018.06, [URL], A novel CFD approach based on adaptive mesh refinement (AMR) technique is being developed for numerical simulation of violent free surface flows. CIP method is applied to the flow solver and tangent of hyperbola for interface capturing with slope weighting (THINC/SW) scheme is implemented as the free surface capturing scheme. The PETSc library is adopted to solve the linear system. The linear solver is redesigned and modified to satisfy the requirement of the AMR mesh topology. In this paper, our CFD method is outlined and newly obtained results on numerical simulation of violent free surface flows are presented..
4. Cheng Liu, Changhong Hu, An adaptive multi-moment FVM approach for incompressible flows, Journal of Computational Physics, 10.1016/j.jcp.2018.01.006, 359, 239-262, 2018.04, [URL], In this study, a multi-moment finite volume method (FVM) based on block-structured adaptive Cartesian mesh is proposed for simulating incompressible flows. A conservative interpolation scheme following the idea of the constrained interpolation profile (CIP) method is proposed for the prolongation operation of the newly created mesh. A sharp immersed boundary (IB) method is used to model the immersed rigid body. A moving least squares (MLS) interpolation approach is applied for reconstruction of the velocity field around the solid surface. An efficient method for discretization of Laplacian operators on adaptive meshes is proposed. Numerical simulations on several test cases are carried out for validation of the proposed method. For the case of viscous flow past an impulsively started cylinder (Re=3000,9500), the computed surface vorticity coincides with the result of the body-fitted method. For the case of a fast pitching NACA 0015 airfoil at moderate Reynolds numbers (Re=10000,45000), the predicted drag coefficient (C<sub>D</sub>) and lift coefficient (C<sub>L</sub>) agree well with other numerical or experimental results. For 2D and 3D simulations of viscous flow past a pitching plate with prescribed motions (Re=5000,40000), the predicted C<sub>D</sub>, C<sub>L</sub> and C<sub>M</sub> (moment coefficient) are in good agreement with those obtained by other numerical methods..
5. Cheng Liu, Changhong Hu, An immersed boundary solver for inviscid compressible flows, International Journal for Numerical Methods in Fluids, 10.1002/fld.4399, 85, 11, 619-640, 2017.12, [URL], In this paper, a simple and efficient immersed boundary (IB) method is developed for the numerical simulation of inviscid compressible Euler equations. We propose a method based on coordinate transformation to calculate the unknowns of ghost points. In the present study, the body-grid intercept points are used to build a complete bilinear (2-D)/trilinear (3-D) interpolation. A third-order weighted essentially nonoscillation scheme with a new reference smoothness indicator is proposed to improve the accuracy at the extrema and discontinuity region. The dynamic blocked structured adaptive mesh is used to enhance the computational efficiency. The parallel computation with loading balance is applied to save the computational cost for 3-D problems. Numerical tests show that the present method has second-order overall spatial accuracy. The double Mach reflection test indicates that the present IB method gives almost identical solution as that of the boundary-fitted method. The accuracy of the solver is further validated by subsonic and transonic flow past NACA2012 airfoil. Finally, the present IB method with adaptive mesh is validated by simulation of transonic flow past 3-D ONERA M6 Wing. Global agreement with experimental and other numerical results are obtained..
6. Cheng Liu, Changhong Hu, A Second Order Ghost Fluid Method for an Interface Problem of the Poisson Equation, Communications in Computational Physics, 10.4208/cicp.OA-2016-0155, 22, 4, 965-996, 2017.10, [URL], A second order Ghost Fluid method is proposed for the treatment of interface problems of elliptic equations with discontinuous coefficients. By appropriate use of auxiliary virtual points, physical jump conditions are enforced at the interface. The signed distance function is used for the implicit description of irregular domain. With the additional unknowns, high order approximation considering the discontinuity can be built. To avoid the ill-conditioned matrix, the interpolation stencils are selected adaptively to balance the accuracy and the numerical stability. Additional equations containing the jump restrictions are assembled with the original discretized algebraic equations to form a new sparse linear system. Several Krylov iterative solvers are tested for the newly derived linear system. The results of a series of 1-D, 2-D tests show that the proposed method possesses second order accuracy in L norm. Besides, the method can be extended to the 3-D problems straightforwardly. Numerical results reveal the present method is highly efficient and robust in dealing with the interface problems of elliptic equations..
7. Cheng Liu, Changhong Hu, Adaptive THINC-GFM for compressible multi-medium flows, Journal of Computational Physics, 10.1016/j.jcp.2017.04.032, 342, 43-65, 2017.08, [URL], In this paper, a THINC (tangent of hyperbola for interface capturing) (Xiao F. et al., 2005) [26] coupled with GFM (Ghost Fluid Method) is proposed for numerical simulation of compressible multi-medium flows. The THINC scheme, which was first developed for incompressible flows, is applied for capturing the distorted material interface of compressible flows. The hybrid WENO (weighted essentially non-oscillatory) scheme with the blocked structured adaptive mesh refinement (AMR) method is implemented. Load balancing is considered in the parallel computing. Several well documented numerical tests are performed and the results show that the THINC scheme behaviors better in mass conservation. It is the first endeavor to implement THINC scheme with adaptive mesh for computing the compressible multiphase problems. The shock wave–helium bubble interaction test reveals that the present method is efficient in prediction of the deformed interface. The solver is further validated by shock wave impact SF6 interface with square, rectangle, forward and backward triangle shapes in which the wave positions and intersecting angles are compared quantitatively. Finally, the collapse of an air bubble under shock in water is simulated, global agreement with experimental and other numerical results are obtained..

9. Xuhui Li, Fei Jiang, Changhong Hu, Analysis of the accuracy and pressure oscillation of the lattice Boltzmann method for fluid–solid interactions, Computers & Fluids, 10.1016/j.compfluid.2016.01.015, 129, 33-52, 2016.04, Investigations have been conducted to analyze the accuracy of the ghost fluid immersed boundary lattice Boltzmann method and the conventional interpolation/extrapolation bounce-back schemes. The intrinsic sources of pressure oscillation for numerical simulation of moving boundary flows have also been inves- tigated. An existing bilinear ghost fluid immersed boundary lattice Boltzmann method (BGFM) (Tiwari and Vanka, 2012) and a proposed quadratic ghost fluid immersed boundary lattice Boltzmann method (QGFM) have been compared with Guo’s second-order extrapolation bounce-back scheme (Guo et al.) and the linear and quadratic interpolation bounce-back scheme (LIBB, QIBB) (Bouzidi et al., 2001; Lalle- mand and Luo, 2003). To study the numerical pressure oscillations in the moving boundary problem, (i) three existing refilling techniques and one proposed refilling technique are compared; (ii) three col- lision models, including the single-relaxation-time model, the multiple-relaxation-time model and the two-relaxation-time model, are investigated; (iii) two force evaluation schemes, a Galilean invariant mo- mentum exchange method Wen et al. and a stress integration method Inamuro et al., are considered. The accuracy and the performance in pressure oscillation suppression for the studied numerical approaches are compared and discussed by five numerical examples: an eccentric cylinder flow, a Cylindrical Couette flow, an impulsively started cylinder in a channel, an oscillation cylinder in calm water and a particle suspension problem. The numerical results indicate that the accuracy of QGFM scheme is comparable to Guo’s scheme while the accuracy of BGFM is worse than both of them. The QIBB scheme shows the best performance in the space convergence accuracy among all the schemes. Selection of the collision model, refilling technique and force evaluation scheme affect the pressure oscillation phenomenon in moving boundary simulations remarkably..

Fei Jiang, Changhong Hu, Numerical Simulation of a Rising CO2 Droplet in the Initial Accelerating Stage by a Multiphase Lattice Boltzmann Method, Applied Ocean Research, 10.1016/j.apor.2013.06.005, 45, 0, 1-9, 2014.03, A multi-phase flow model which applies lattice Boltzmann method (LBM) is developed for numerical simulation
of the initial accelerating stage of a rising CO 2 droplet in the deep ocean. In the present LBM model, a
multiple-relaxation time (MRT) collision operator is adopted to increase the numerical stability, and a color
model is used to treat the two-phase fluid. A domain shift scheme is proposed to make the long distance
calculation available. The computation is accelerated by using the GPU computing and correspondent parallel
implementation techniques are developed. The proposed numerical model is first validated against several
benchmark problems: Laplace law test, binary Poiseuille flow problem and rise of a toluene droplet. Then
numerical simulation of a liquid CO 2 droplet rising from quiescence to its steady state is carried out and the
results are compared to a laboratory experiment. Excellent agreement is obtained on both terminal velocity
and variation of droplet shape..

Kangping Liao, Changhong Hu, A coupled FDM–FEM method for free surface flow interaction with thin elastic plate, Journal of Marine Science and Technology, 10.1007/s00773-012-0191-0, 18, 1, 1-11, 2013.03, A partitioned approach by the coupling finite difference method (FDM) and the finite element method
(FEM) is developed for simulating the interaction between free surface flow and a thin elastic plate. The FDM, in
which the constraint interpolation profile method is applied, is used for solving the flow field in a regular fixed
Cartesian grid, and the tangent of the hyperbola for interface capturing with the slope weighting scheme is used for
capturing free surface. The FEM is used for solving structural deformation of the thin plate. A conservative
momentum-exchange method, based on the immersed boundary method, is adopted to couple the FDM and the
FEM. Background grid resolution of the thin plate in a regular fixed Cartesian grid is important to the computational
accuracy by using this method. A virtual structure method is proposed to improve the background grid resolution
of the thin plate. Both of the flow solver and the structural solver are carefully tested and extensive validations
of the coupled FDM–FEM method are carried out on a benchmark experiment, a rolling tank sloshing with a thin
elastic plate..
13. Changhong Hu, Makoto Sueyoshi, Fei Jiang, Kiminori Shitashima,Tetsuo Yanagi, Rise and Dissolution Modeling of CO2 Droplet in the Ocean, Journal of Novel Carbon Resource Sciences, 7, 12-17, 2013.02, A numerical approach is proposed to study the behavior of a natural carbon dioxide (CO2) droplet leaked from the
seafloor. Motion and deformation of the droplet at the initial stage are simulated by a lattice Boltzmann multi-phase
method to obtain the terminal velocity. The whole process of droplet rise and dissolution is modeled by a simplified
analytical method. The in-situ experiment case on a natural CO2 droplet at the Okinawa Trough (Shitashima, et al.1))
is studied by using the proposed numerical model. Numerical experiments show strong dependency between the
terminal velocity and the droplet density. The phenomena obtained in the on-sea observation are discussed by the
present numerical study..
14. Xizeng Zhao, Changhong Hu, Numerical and experimental study on a 2-D floating body under extreme wave conditions, Applied Ocean Research, 10.1016/j.apor.2012.01.001, 35, 1-13, 2012.03, This paper presents further developments of a constrained interpolation profile (CIP)-based Cartesian grid method (Hu et al. [29]) to model nonlinear interactions between extreme waves and a floating body, which is validated against to a newly performed experiment. In the experiment, three kinds of waves (regular wave, focused wave and combined regular and focused wave) are generated and a box-shaped floating body with a superstructure is used. Validation computations on the experiment are performed by the improved CIP-based Cartesian grid method, in which the THINC/WLIC scheme (THINC: tangent of hyperbola for interface capturing; WLIC: Weighed line interface calculation), is used for interface capturing. The highly nonlinear wave-body interactions, including large amplitude body motions and water-on-deck are numerically investigated through implementation of focused wave input to the CIP-based method. Computations are compared with experimental results and good agreement is achieved. The effects of the water-on-deck phenomena and different input focus positions on the body response are also dealt with in the research..
