Core-pressure alleviation for a wall-normal vortex by active flow control

Q Liu, B An, M Nohmi, M Obuchi… - Journal of Fluid …, 2018 - cambridge.org
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 model …

Active flow control of a pump-induced wall-normal vortex with steady blowing

Q Liu, B An, M Nohmi, M Obuchi… - Journal of Fluids …, 2020 - asmedigitalcollection.asme.org
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 …
