October 10, 2014, 01:23	Need help on K-Kl-Omega for Low Re Flow (50,000 to 200,000) over airfoil	#1
devanson New Member Dinesh Babu Join Date: Oct 2010 Location: Bangalore Posts: 23 Rep Power: 16	Hi, I need your help on setting a Low Re Flow (50K to 200K) over an airfoil. My main aim is to capture the Laminar Separation bubble. I already did some work around. Created a good fine (wall y+<=1) C-Domain structured mesh over airfoil. Front, top & Bottom set to Velocity inlet and Downstream end set to Pressure outlet. When I run the steady flow case with default K-Kl-Omega settings, my solution is not converging at all. So, need your help in setting up this case and convergence. __________________ Dinesh Babu CFD Engineer
