◆ cs_turbulence_rij()

Solve the $R_{ij} - \epsilon$ for incompressible flows or slightly compressible flows for one time step.

Please refer to the $R_{ij} - \epsilon$ model section of the theory guide for more informations, as well as the turrij section.

Parameters

[in]	phase_id	turbulent phase id (-1 for single phase flow)
[in]	ncesmp	number of cells with mass source term
[in]	icetsm	index of cells with mass source term
[in]	itypsm	mass source type for the variables
[in]	smacel	values of the variables associated to the mass source (for ivar=ipr, smacel is the mass flux) !

Clip the turbulent Reynods stress tensor and the turbulent dissipation (coupled components version).

Parameters

[in]	phase_id	turbulent phase id (-1 for single phase flow)
[in]	n_cells	number of cells

void cs_turbulence_rij_compute_rusanov ( void )

Compute Rusanov equivalent diffusivity of the model.

void cs_turbulence_rij_init_by_ref_quantities	(	cs_real_t	uref,
		cs_real_t	almax
	)

Initialize Rij-epsilon variables based on reference quantities.

If uref is not provided (0 or negative), values are set at a large negative value (-cs_math_big_r) to allow for later checks.

Parameters

[in]	uref	characteristic flow velocity
[in]	almax	characteristic macroscopic length of the domain

void cs_turbulence_rij_mu_t ( int phase_id )

void cs_turbulence_rij_solve_alpha	(	int	f_id,
		int	phase_id,
		cs_real_t	c_durbin_l
	)

Solve the equation on alpha in the framework of the Rij-EBRSM model.

Also called for alpha of scalars for EB-DFM.

Parameters

[in]	f_id	field id of alpha variable
[in]	phase_id	turbulent phase id (-1 for single phase flow)
[in]	c_durbin_l	constant for the Durbin length !
