Abstract: Tip leakage flow (TLF) is a typical flow phenomenon in the internal flow of axial-flow pumps that has a serious impact on their safety and stability. In this study, numerical simulations are performed to investigate the ...

Abstract: Abstract. Marine propulsion is a significant source of noise. In this study, a hybrid method coupling computational fluid dynamics and the acoustic-analogy theory is adopted to calculate the unsteady flow field and sound ...

Abstract: This paper is to solve the problem of poor stability of bidirectional shaft pumps, under reverse and low-head condition. In this study, computational fluid dynamics (CFD) calculations are carried out and verified by model ...
