◆ cs_turbulence_kw()

void cs_turbulence_kw ( int phase_id )

Solve the k-omega equations.

Solve the $k - \omega$ SST for incompressible flows or slightly compressible flows for one time step.

Parameters

[in] phase_id turbulent phase id (-1 for single phase flow)

void cs_turbulence_kw_mu_t ( int phase_id )

Calculation of turbulent viscosity for the $k - \omega$ SST model.

$\mu_T = \rho A1 \dfrac{k}{\max(A1 \omega; \; S f_2)}$

with

$S = \sqrt{ 2 S_{ij} S_{ij}}$

$S_{ij} = \dfrac{\der{u_i}{x_j} + \der{u_j}{x_i}}{2}$

and $f_2 = \tanh(arg2^2)$

$arg2^2 = \max(2 \dfrac{\sqrt{k}}{C_\mu \omega y}; \; 500 \dfrac{\nu}{\omega y^2})$

where is the distance to the wall.

$\divs{\vect{u}}$ is calculated at the same time than for use in cs_turbulence_kw.

Parameters

[in] phase_id turbulent phase id (-1 for single phase flow)

$\mu_T = \rho A1 \dfrac{k}{\max(A1 \omega; \; S f_2)}$

with

$S = \sqrt{ 2 S_{ij} S_{ij}}$

$S_{ij} = \dfrac{\der{u_i}{x_j} + \der{u_j}{x_i}}{2}$

and $f_2 = \tanh(arg2^2)$

$arg2^2 = \max(2 \dfrac{\sqrt{k}}{C_\mu \omega y}; \; 500 \dfrac{\nu}{\omega y^2})$

where is the distance to the wall.

$\divs{\vect{u}}$ is calculated at the same time than for use in cs_turbulence_kw.

Parameters

[in] phase_id turbulent phase id (-1 for single phase flow)
