Vorticity Fig 1. Results of a CFD calculation of flow impinging on a block (a) streamlines, (b)velocity vector plot of upper half of the flow and (c) velocity vector plot, close up view revealing more details. (From Cengel and Cimbabla)
Vorticity Fig 3. Contour plots of the vorticity field due to flow impinging on a block as produced by a CFD simulation. Only the upper half is due to symmetry. Dark regions represent large negative vorticity and light regions represent large positive vorticity. Fig 2. Contour plots of the pressure field due to flow impinging on a block as produced by a CFD simulation.
