CFD POST——swirl flow: how to show the inner swirl flow

sidda · March 13, 2012, 09:02

dear all,
As shown in the former picture, the swirl flows exist both in the center and in the wall (boundary) of the draft tube. But the swirl flow in the center is the only one I need. Does anybody know how to deprive of the surrounding swirl flows?
The ideal result should be like the one followed.

First of all, this assumes your simulation has predicted a swirl flow like what what you show. But assuming the flow actually contains a swirl then an isosurface of pressure should show it. Also streamlines should show it in a different way.
