Detailed Description

Computing rotation/curvature correction for eddy-viscosity models. The subroutine is called for the linear eddy viscosity RANS models, when the option irccor = 1 is verified.

Two type of rotation/curvature correction are computed, depending on the specific eddy-viscosity model:

• itycor = 1: - Cazalbou correction (variable Ce2 coefficient in the destruction term of dissipation equation)
  • default correction for type models, including elliptic relaxation/blending models (iturb = 20, 21, 50 or 51)
• itycor = 2: - Spalart-Shur correction (production terms are multiplied by a rotation function)
  • default correction for SST or Spalart-Allmaras (iturb = 60 or 70)
