10. Turbulence Modeling # K-W SST Model with High Resolution
Accounts for the transport of the turbulence shear stress and gives
very highly accurate predictions of the onset and the amount of
flow separation under adverse pressure gradients
Improve the accuracy for the predictions of the flow separation from
a smooth surface : Important phenomenon in many industrial fields,
particularly for airplane industries
