Abstract: Inspired by the silent flight capability of owls, the serrated trailing-edge design is recognized as an effective method to control trailing-edge interference noise arising from turbulent boundary layers. Based on the ...

Abstract: 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 ...

Abstract: On-orbit refueling and space circulation technologies involve the use of a space micropump to transport gas–liquid mixed fluids, which affects the gas–liquid mass transfer and dynamic behaviors. To predict dynamic mass ...

Abstract: Complex energy conversion and energy dissipation occur in pump-turbines during the load rejection process. However, the underlying fluid mechanism is not clear. In order to solve these problems, in this study, a three-dimensional ...

Abstract: Pump performance characteristics of pump turbines in transient processes are significantly different from those in steady processes. In the present paper, transient processes of a flow rate that increased and decreased in ...
