Turbulence model for wing with deflected flap
I need to run a simulation on a wing with a flap deflection of 30 degrees. The airplane is flying at 40 m/s at sea level. Would the k-omega SST be a good turbulence model to use for this case? Or would you suggest something else?
Further, how do I estimate turbulence intensity and freestream viscosity ratio???
Any suggestions are welcome!
I suppose you are talking about full-scale airplane, so that Re is of order 10^6-10^7. In this case the flow will be tubulent almost everywhere and you can use simpler turbulence models such as S-A model. Multi-equation transitional turbulence models shold be more accurate in theory, but in practice they are usually not without a sophisticated user input.
