Much Difference on my airfoil simulation
4 Attachment(s)
Hi All,
I'm simulating 2 kind of turbulance model on an airfoil, i.e K Epsilon & SST. but there is much differences. I dont know where is my fault!! Help me out this problem, Thanks:D teguhtf P.S. I attach the report and figure of each turbulence condition |
It doesn´t look good to me, how are the residuals??

Hi Figd84
Thanks for your reply. my simulation has converged on iteration. Btw, How i can see convergence on residual graph?? Because I think if the solution has converged, i ignore the residual.:o Thank You teguh PS. I'll Post my residual graph later |
From your pictures I can't see any outlet (I see only a blue edge which means inlet).
If I am right, then it might be your error, since you don't have mass conservation |
I'm sorry to be late on the reply. I've focused on my fabrication on the turbine for a while.
Yes, You are right. I use wrong BC.^^ I've tried some of type of BC and take a note on it. Now, I'm still working by up & down wall (free slip) and the inlet is velocity inlet & outlet is press outlet. thank's teguhtf |
