dc.description.abstract | The present paper deals with a numerical simulation of cryogenic cavitating flows around turbopump inducer in liquid rocket. Recently, we have developed an accurate and efficient baseline numerical scheme for the computations of all-speed two-phase flows. Firstly, by extending such progress, we conduct some modification of preconditioning technique and propose an accurate and efficient numerical method to deal with the computations of cryogenic two-phase flows. Secondly, we compute and compare, for the purpose of validating the proposed method, two-dimensional/axis-symmetric cryogenic cavitation flows around hydrofoil and ogive. Finally, numerical simulations of three-dimensional KARI turbopump inducer are carried out under various flow conditions with water and cryogenic fluids, and we examine the differences in inducer flow physics depending on the working fluids. | - |
