Optimization of Structural Parameters and Cavitation Suppression in Control Valves Based on P-WOA [PDF]
Journal of Applied Fluid MechanicsA control valve is a critical component in water supply systems, controlling pressure, flow, and direction. However, cavitation, caused by low pressure in the valve cavity, disrupts flow and leads to cavitation damage, vibration, and noise, affecting ...

Prandtl–Batchelor flow past a flat plate with a forward-facing flap [PDF]
, 1984 Two-dimensional steady inviscid flow past an inclined flat plate with a forward-facing flap attached to the rear edge is considered for the case when a vortex sheet separates from the leading edge of the flat plate and reattaches at the leading edge of ...
