Hi,

may I know how to describe this phenomena? This is taken from a acoustics power level contour.

[Danielgkh]

Are they due to flow separation?

[Karthik Remella]

Hello This could be because of many reasons and the plot does not give us much information to understand the flow field. Please plot the velocity and pressure contours to understand the flow.

[Danielgkh]

the velocity and pressure contours are as follow
Velocity contour
Static pressure contour
I am trying to find a word for it, but not sure if flow separation the right one.

[Karthik Remella]

Hello If you wish to check for flow separation, please plot the shear stress along the wall or look at the velocity vector near the wall to visualize.
