Good afternoon
Trying to simulate roughness (0.0003m to 0.0007m roughness height) in a nozzle and investigate the effect of roughness on mass flow rate but there is a problem. I get excessive temp. here is a screenshot of the contour of static temperature:  As you can see at the throat this excessive temp. has taken place. why? Any idea to figure it out? |
