... is modified to clarify the rapid head drop of a cavitation flow within a test centrifugal pump, and it is used to simulate the cavitation flow. Local entropy generation method is used to analyze the cavitation flow with varying net positive suction head. The magnitude of entropy generation in different types...

...Shijie Zhang; Zhifeng Yao; Hongfei Wu; Qiang Zhong; Ran Tao; Fujun Wang Due to the ignorance of the effect of the water–vapor interface on the cavitation flow field, the standard k– ε turbulence model (ST model) may overestimate the turbulent viscosity. It is unable to simulate cavitation shedding...

...Deyou Li; Zhipeng Ren; Yu Li; Boxuan Miao; Ruzhi Gong; Hongjie Wang Liquid oxygen turbopumps are an important component of rocket engines. The instability induced by cavitation flow in turbopumps has received considerable attention because of thermodynamic effects. In this study, unsteady numerical...
