Active flow control of a pump-induced wall-normal vortex with steady blowing
Qiong Liu, Byungjin An, Motohiko Nohmi +2
The emergence of a submerged vortex upstream of a pump can reduce pump intake efficiency and cause structural damage. In this study, we consider the use of active flow control with…

Core-pressure alleviation for a wall-normal vortex by active flow control
Qiong Liu, Byungjin An, Motohiko Nohmi +2
We consider the application of active flow control to modify the radial pressure distribution of a single-phase wall-normal vortex. The present flow is based on the Burgers vortex…
