Hi All,

I'm running an external case for a NACA0012 wing and I'm getting reversed flow at the flow field outlet. Do you think this is something I should worry about? I'm going by the assumption that its far enough away from the point of interest not to matter a whole lot. My flow field boundaries are 20c away all around the wing except in front where its 15c.

Cheers, and thanks in advance. Ben

check your gauge pressure value at outlet. if it is different at different outlet boundaries then u might get reversed flow. or if u ar specifying some non-zero gauge pressure at outlet keeping oprating pressure Atmospheric and in reality it should match with Atmospheric conditions then too u can get reversed flow.

when i saw this forum,i also have some question here about the scavenging simulation for two-stroke engine.When i run the modelling,similar problem like above problem (reversed flow),i try to change the value of control solution setting.I dont know how solve the reversed flow.hopes anyone can help me:.,this my email.,ir_nik@yahoo.co.uk
