What is it about?
Both SST and its wall-distance-free (WDF) variant are developed for simple and complex heat transfer problems. A new eddy-viscosity bound and a variable turbulent Prandtl number formulation are included to accommodate better predictions for flows with separation and reattachment.

Why is it important?
No complicated heat flux modeling is needed. A simple gradient type modeling is sufficient to predict the heat transfer rate, reasonably.
