Best Turbulence model for Wind turbine
 

Hi

I am doing a transient rotor simulation of a horizontal axis wind turbine and I want to know which turbulence model is good for this simulation and which is commonly used by the experts ?

Use the SST model for everything unless you have a good reason to know it will not work. That is the general advice. And SST works especially well on blade flows so it is definitely the one to use for your case.
