- Research on the flow mechanism of cavitation instabilities in inducers toward their advance detection, control and suppression
keyword : Inducer, Cavitation instabilities, Advance detection
1998.04The attachment of pump inducer upstream of main impeller is a powerful method to improve the cavitation performance. However under the severe condition of suction pressere at partial flow rate, cavitation induced oscillation occurrs and stable pump operation becomes difficult. This oscillation is investigated in order to elucidate the mechanism of oscillation occurring and to develop the advance detection system and suppression devices.. - Experimental/Numerical studies on basic charactersitics of unsteady cavitating flow around hydrofoils and cascades
keyword : Cavitation, Unsteady Flow
1998.04Experimental/Numerical studies on basic charactersitics of unsteady cavitating flow around hydrofoils and cascades. - Theoretical/numerical modeling of thermodynamic effect of cavitation (real fluid effects of thermosensible fluid) and its application to the unsteady cavitation analysis
keyword : Cavitation, Thermodynamic effect
2005.04Theoretical/numerical modeling of thermodynamic effect of cavitation (real fluid effects of thermosensible fluid) and its application to the unsteady cavitation analysis . - Reseach and development of simplified ducted Darriues hydroturbine for utilization of extra low head sites.
keyword : Darriues hydroturbine, Extra low head hydropower, Low cost
1998.04Reseach and development of simplified ducted Darriues hydroturbine for utilization of extra low head sites.. - Research and develomement of gas-liquid two phase flow centrifugal pump and its application to large capacity micro-bubble generator
keyword : Centrifugal pump, Gas liquid two-phase flow, Microbubble
1998.04Research and develomement of gas-liquid two phase flow centrifugal pump and its application to large capacity micro-bubble generator. - Research on high performance design of contra-rotating axial flow pump
keyword : Turbomachinery, Axial flow pump, Contra-rotating rotors, High performance
1999.04There is a demand for a small-sized and high-speed axial flow pump with high efficiency for energy and CO2 prolems. An axial flow pump with contra-rotating rotors, instead of with rotor-stator, has been proposed to achieve the demand. In order to develop the design guiding principle, The experimental and computational works are carried on..
