Function Documentation

◆ cs_f_combustion_reconstruct_variance()

void cs_f_combustion_reconstruct_variance ( int iprev)

◆ cs_steady_laminar_flamelet_source_terms()

void cs_steady_laminar_flamelet_source_terms ( cs_field_t * f_sc,
cs_real_t smbrs[],
cs_real_t rovsdt[] )

Defines the source terms for the soot mass fraction and the precursor number for soot model of Moss et al for one time step.

The equations read: $ rovsdt \delta a = smbrs $

$ rovsdt $ et $ smbrs $ could already contain source term and don't have to be erased but incremented.

For stability sake, only positive terms should be add in $ rovsdt $. There is no constrain for $ smbrs $.

For a source term written $ S_{exp} + S_{imp} a $, source terms are: $ smbrs = smbrs + S_{exp} + S_{imp} a $ $ rovsdt = rovsdt + \max(-S_{imp},0) $

Here are set $ rovsdt $ and $ smbrs $ containning $ \rho \Omega $

  • $ smbrs $ in $ kg_a.s^{-1} $ (ex: for velocity: $ kg.m.s^{-2} $, for temperature: $ kg.C.s^{-1} $, for enthalpy: $ J.s^{-1} $)
  • $ rovsdt $ en $ kg.s^{-1} $
