High vorticity

WebThe primary feature of a vortex is that planar vorticity dominates over planar deviatoric strain rate and the flow becomes swirling in the cross-sectional plane which results (i) in the occurrence of a local pressure minimum in a plane and (ii) in elliptical deviatoric flow patterns of the projected planar velocity field near a point as discussed … WebApr 12, 2024 · Under different boundary constraint degrees, the vorticity attenuated to 10% of the initial vorticity. For the flow around a square cylinder, the final attenuation degree of the vorticity of the vortex street was unrelated to the distribution, shape, and motion law of the vortex street caused by the boundary constraints.
