Function Documentation

◆ cs_get_glob_cavitation_parameters()

cs_cavitation_parameters_t* cs_get_glob_cavitation_parameters ( void )

◆ cs_get_glob_vof_parameters()

cs_vof_parameters_t* cs_get_glob_vof_parameters ( void )

◆ cs_vof_compute_linear_rho_mu()

void cs_vof_compute_linear_rho_mu ( const cs_domain_t * domain )

Compute the mixture density, mixture dynamic viscosity given fluid volume fractions and the reference density and dynamic viscosity $\rho_l, \mu_l$ (liquid), $\rho_v, \mu_v$ (gas).

Computation is done as follows on cells:

$\rho_\celli = \alpha_\celli \rho_v + (1-\alpha_\celli) \rho_l,$

$\mu_\celli = \alpha_\celli \mu_v + (1-\alpha_\celli) \mu_l,$

A similar linear formula is followed on boundary using fluid volume fraction value on the boundary.

◆ cs_vof_log_mass_budget()

void cs_vof_log_mass_budget ( const cs_domain_t * domain )

Write in main log the global mixture mass budget:

$\sum_i\left( |\Omega_i|\dfrac{\alpha_i^n - \alpha_i^{n-1}}{\Delta t} + \sum_{j\in\Face{\celli}}\left(\rho\vect{u}\vect{S}\right)_{ij}^n \right).$

◆ cs_vof_update_phys_prop()

void cs_vof_update_phys_prop ( const cs_domain_t * domain )

Compute the mixture density, mixture dynamic viscosity and mixture mass flux given the volumetric flux, the volume fraction and the reference density and dynamic viscosity $\rho_l, \mu_l$ (liquid), $\rho_v, \mu_v$ (gas).

For the computation of mixture density, mixture dynamic viscosity, see cs_vof_compute_linear_rho_mu.

Computation of mass flux is as follows:

$\left( \rho\vect{u}\cdot\vect{S} \right)_\ij = \\ \left\lbrace \begin{array}{ll} \rho_\celli (\vect{u}\cdot\vect{S})_\ij &\text{ if } (\vect{u}\cdot\vect{S})_\ij>0, \\ \rho_\cellj (\vect{u}\cdot\vect{S})_\ij &\text{ otherwise }, \end{array} \right.$

$\left( \rho\vect{u}\cdot\vect{S} \right)_\ib = \\ \left\lbrace \begin{array}{ll} \rho_\celli (\vect{u}\cdot\vect{S})_\ib &\text{ if } (\vect{u}\cdot\vect{S})_\ib>0, \\ \rho_b (\vect{u}\cdot\vect{S})_\ib &\text{ otherwise }. \end{array} \right.$
