Pressure contour seems wrong???
 
Dear Mr. or Ms.:

I am simulating a turbulent flow problem with Standard k-epslon model.My problem setup are as follows: 1. velocity inlet 2. pressure outlet 3. K-Epslon turbulent model

After iteration, I find that the velocity distribution seems right. But the pressure distribution seems wrong, because where the static pressure is large, the velocity pressure is large too. So this results in the total pressure difference between different points is much bigger than I expected.

For example: the fluid flow through a sharp-expansion duct, before the sharp-expansion the total pressure is 20000 Pa, but after the expansion the total pressure is 0 Pa. I think it's a wrong iteration resolution.

But can you tell me why I get this wrong sovlement?

Thank you very much. Any points are welcomed.

Sincerely yours, Harry.
