Computations of Cryogenic Cavitating Flows around Turbopump Inducer

摘要：

　　This paper deals with the numerical computations of cryogenic cavitating flows around turbopump inducer in liquid rocket.The baseline numerical fluxes for the computations of all-speed two-phase flows (two-phase RoeM and AUSMPW+ schemes) are extended for treating general equation of states,and improved preconditioning techniques are developed for robust and efficient computations in low-speed region.As a validation step for such progress,cryogenic cavitating flows around hydrofoil and ogive are computed.Finally,numerical simulations of three-dimensional KARI turbopump inducer are carried out under various flow conditions with water and cryogenic fluids,and the difference in inducer flow physics depending on the working fluids are examined.
