Two equation turbulence models solver settingsHello,
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 __________________________________________________ _______ Steady Pressure Based Implicit Formulation Absolute velocity formulation Green-Gauss Cell Based Gradient option ************* Pressure_Velocity coupling SIMPLE Discretization Pressure PRESTO!
