Summary: Helps to yield more accurate flow results such as pressure and velocity fields in devices like cyclones and airfoils with blowing and suction.

A = 1: (On) = Enables the Hellsten Rotation-Curvature correction feature of the SST k-omega turbulence model.
A = 0: (Off) = The correction feature is disabled. (Default)
Description
The RC model sensitizes the net turbulence generation to streamline curvature, particularly near the walls. For convex curvature, it increases generation and causes the flow to separate earlier. For concave curvature, it decreases generation of turbulent energy and hence retards separation.
This helps to yield more accurate flow results such as pressure and velocity fields in devices like cyclones and airfoils with blowing and suction. More information can be found here http://turbmodels.larc.nasa.gov/sst.html
This flag only works with the SST k-omega turbulence model.
