Two equation turbulence models solver settings
I will be grateful for your help. I am trying to make to converge solution for a low Re flow past to 2D airfoil with Realizable KE (wall enchanced treatment) and KW/KW SST transitional models as well.
There is no problem with convergence for one equation SA model and results are more or less satisfactory, but once I switch to 2 equation models I am going in a trouble.
I have checked y+, it is within the limits .1 to 1.
So, there could be two reasons for failure
1) These models are not suitable for analysing airfoils at Re about 10^5
2) My solver setting are wrong
Could the second be the case?
I will be grateful if you could help me:
Here I list the solver settings
Pressure Based Implicit Formulation
Absolute velocity formulation
Green-Gauss Cell Based Gradient option
Pressure_Velocity coupling SIMPLE
Momentum SECOND ORDER UPWIND
Turbulent kinetik energy SECOND ORDER UPWIND
Specific dissipation rate SECOND ORDER UPWIND
body force 1
I will be grateful for your help
