    In this study, we developed a hybrid approach using the lattice Boltzmann method (LBM) and finite-volume lattice Boltzmann method (FVLBM) to perform efficient aeroacoustic simulations with moving boundaries. An entire domain, including the flow and acoustic fields, was computed using the standard LBM with a Cartesian grid. Local domains around the moving objects were computed using the FVLBM with body-fitted grids. These simulations were coupled using the direct forcing method to consider moving boundaries. The hybrid method was validated for several problems including turbulent flows and flow-induced sounds under low-Mach-number conditions. These validation problems covered flows with Reynolds numbers up to 2.0×105 and Mach numbers less than 0.2. In the simulations of the aeolian tone generated from stationary and rotating cylinders, the hybrid method results were consistent with those of the conventional methods. In the simulation of the turbulent flow and broadband sound of the isolated airfoil, the hybrid method was 15 times faster than the standard LBM and produced results consistent with the experimental results. Furthermore, the application of a cross-flow fan demonstrated that the hybrid method successfully simulated the flow and acoustic fields around the rotor.

  • Aeroacoustic simulation of bluff bodies with protrusions at moderate Reynolds number Reviewed International journal

    This paper presents an evaluation of passive control methods that employ surface protrusions to mitigate the aerodynamic sound generated from a cylinder wake flow. Building on previous designs optimized for low Reynolds numbers (Re = 150) through adjoint-based aeroacoustic shape optimization, this study investigated the performance under a moderate Reynolds number (Re = 67 000) condition typical of mechanical engineering applications using aeroacoustic simulations based on the lattice Boltzmann method. Three configurations of surface protrusions were tested, all of which were found to significantly reduce the mean drag by at least 45% compared with that of an unmodified circular cylinder. Designs featuring rear protrusions outperformed the conventional splitter plate in terms of the sound reduction performance, with symmetrical protrusions on both the front and rear surfaces achieving a tonal sound reduction of 13 dB. However, a specific protrusion design increased the low-frequency sound owing to the intensified large-scale flow separation. These findings highlight the effectiveness of rear protrusions in suppressing wake oscillations and dipole sound generation in the subcritical Reynolds number range. Moreover, the study revealed the need to tailor the front protrusion shape to the Reynolds number for performance optimization.

    Aerodynamic noise control is important for various engineering applications, including automobiles. To develop effective control methods for the flow and sound of bluff bodies, flow past a cylinder is usually studied as a simplified problem. In this study, a passive control technique using surface protrusions was developed to suppress the aeolian tone generated by a two-dimensional laminar flow past a circular cylinder. Protrusions were created on the front and rear surfaces of the cylinder using an optimization approach based on the lattice Boltzmann and adjoint methods, allowing the optimization of complex geometries. The computational results revealed that a pair of protrusions on the front surface could stabilize the separated shear layers by fixing the separation points to their tips, whereas a pair of protrusions on the rear surface can stabilize the separated shear layers by interfering with the interaction between the top and bottom shear layers. Consequently, these shapes effectively suppressed the vortex shedding and aeolian tone while decreasing the mean drag. A shape with symmetrical protrusions on the front and rear surfaces reduced the aeolian tone by 3.6 dB.

    It is necessary to reduce the aerodynamic sound generated by fans since they are often used for air-conditioners, which are placed in human living areas, such as homes and offices. To reduce the aerodynamic sound, we focused on the Helmholtz resonator. To develop a resonator-type silencer for the aerodynamic sound of air-conditioners, the present study investigated the flow and acoustic fields around a cross-flow fan with a resonator and the effectiveness of the resonator for blade-passing frequency (BPF) sound using aeroacoustic simulations. As a numerical method, we used the lattice Boltzmann method (LBM), which can simultaneously simulate aerodynamically sound generation in the fan and the acoustic resonance in the resonator. Consequently, the simulation results showed that a reduction of 2.9 dB for the BPF sound can be realized by installing a resonator in the tongue part of the fan casing.

    In this study, we investigated the capability of the immersed boundary-lattice Boltzmann method (IB-LBM) in simulating the broadband sound generated from a cross-flow fan. The present method is based on the lattice Boltzmann equation with the D3Q27 particle velocity model, and the cascaded collision operator was used to stably simulate high-Reynolds-number flows. Furthermore, the direct-forcing approach was used to consider rotating blades in the regular lattice. To capture turbulence eddies in the rotor, we used a high-resolution grid that contained approximately 340 million nodes. The simulation successfully captured the fundamental flow features of the cross-flow fan such as the eccentric vortex, and the simulation results were consistent with the experimental results in terms of the time-averaged velocity distribution at the outlet of the fan. In addition, by resolving turbulent eddies in the impeller, the simulation successfully predicted the broadband sound spectrum in the frequency range of 2 kHz or less.

    Detached eddy simulation of unsteady flow field and prediction of aerodynamic sound in a half-ducted propeller fan
    Three-dimensional structures and unsteady nature of vortical flow fields in a half ducted propeller fan have been investigated by a detached eddy simulation (DES) based on k-ω two-equation turbulence model. The validity of the numerical simulation performed in the present study was demonstrated by the comparison to LDV measurement results. The simulation shows the tip vortex is so strong that it dominates the flow field near the rotor tip. The tip vortex does not impinge on the pressure surface of the adjacent blade directly, however it interacts with the shroud surface and induces a separation vortex on the shroud. Furthermore, this separation vortex interacts with the pressure surface of the adjacent blade. These flow structures cause high pressure fluctuation on the shroud surface and the blade pressure surface. Besides, sound pressure levels were predicted by Ffowcs William-Hawkings equation based on Lighthill's acoustic analogy using the unsteady surface pressure data obtained by DES. As a result, the degree of contribution by each flow structure to overall sound has been estimated quantitatively.

    本研究では、格子ボルツマン法(LBM)に基づく流れ場と音響場の直接解法を用いて、流体騒音の低減を目的とした変分問題を定式化することにより、流体騒音に対する設計パラメータの感度を高精度に評価可能な手法を構築する。本設計感度解析手法によって、実験や数値解析による試行錯誤を繰り返すことなく、従来設計を超える革新的な静音形状を創出することが可能になると期待される。
