I want to make a model for turbulence in Ansys. In the project a fan is used which is completely submerged in water. How to proceed in this situation ?
In my case, the k-w SST model works well. The application of this model, as well as comparisons with other turbulence models, can be found in
"Simulations of the aerodynamic response of circular segments with different corner angles by means of 2D URANS. Impact of turbulence modeling approaches. Eng. Appl. Comput. Fluid Mech. 12(1), 750–779 (2018)."
If you are a beginner, you can try all the turbulence models available in Ansys and check which modeling results providing you the best validation.
