pressure peak near wall at inlet

July 8, 2008, 09:46

Hello,

I have a problem when i simulate a polymer flow through a flow channel. The flow channel is a 90 degree elbow with a diameter of 20mm (2D-Cut = circle).

When I simulate this flow and watch the contours of the pressure in the flow channel I get a very high pressure peak on the first few millimeters of the inlet but only near the wall.

Why do I get this peak and how can I handle this problem?

Thank you much.
