Hello All,
In an axisymmetric inviscid solution (no swirl), I observe that total pressure, being imposed as 101325 Pa at the inlet, varies (reduces) within the domain, especially near the walls. The figure showing non-constant total pressure is attached. I use pressure based coupled solver with third order muscl for all variables except pressure, which is second order. When I select PRESTO, the effect reduces but still continues. What can be the reason of this in an inviscid solution? Regards, Last edited by sercan85; February 11, 2014 at 01:43.

Hello
I still suffer dfrom this problem. There is no viscosity in inviscid solver so this should be a numerical error in entropy. Solver: pressure based coupled solver Is there a solution for this? Regards, Sercan |
