	Compute rotation/curvature correction for eddy-viscosity models. More...

Detailed Description

Compute rotation/curvature correction for eddy-viscosity models.

Two types of rotation/curvature correction can be 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 (model = 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

Function Documentation

cs_turbulence_rotation_correction()

void cs_turbulence_rotation_correction	(	const cs_real_t	dt[],
		cs_real_t	rotfct[],
		cs_real_t	ce2rc[]
	)

Compute rotation/curvature correction for eddy-viscosity models.

This function is called for the linear eddy viscosity RANS models, when irccor = 1 is verified.

Parameters

[in]	dt	time step (per cell)
[out]	rotfct	rotation function of Spalart-Shur correction at cell center
[out]	ce2rc	modified ce2 coeficient of Cazalbou correction at cell center
