Reply To: RADIAL DYNAMIC PRESSURE DISTRIBUTION IS INCORRECT?

So it is indeed a slower moving flow at the aft of the impeller hub as can be seen by the smaller in size vectors, which are scaled based on the velocity magnitude. So this can explain the lower dynamic pressure in this region.

Also it seems like you have a higher refinement in the stator inlet rather than the stator outlet. Inlet flow will be mostly undisturbed and uniform while the flow after the impeller will be highly rotating, so maybe a more refined mesh is needed there.
