Detailed Description

Main physical model parameters for the Lagrangian module

Field Documentation

◆ agglomeration

int agglomeration
  • 0: no agglomeration model
  • 1: agglomeration model used

◆ clogging

int clogging
  • 0: no clogging model
  • 1: clogging model

◆ consolidation

int consolidation
  • 0: no consolidation model
  • 1: consolidation model

◆ deposition

int deposition
  • 0: no deposition model
  • 1: depositionion model

◆ dlvo

int dlvo

◆ fouling

int fouling

◆ fragmentation

int fragmentation
  • 0: no fragmentation model
  • 1: fragmentation model used

◆ idiffl

int idiffl

Suppress the crossing trajectory effect (if set to 1), making turbulent dispersion for the particles identical to the turbulent diffusion of fluid particles. Default is off if modcpl = 1, on if modcpl = 0).

◆ idistu

int idistu

Activation of the turbulent dispersion (on: 1; off). Default is on; This is compatible with RANS and LES turbulent models ( $k-\varepsilon$, $R_{ij}-\varepsilon$, v2f or $k-\omega$).

◆ modcpl

int modcpl

Activates (1) or not (0) the assumption that we have regular particles. When set to, 0 then the particles are assumed to be fluid particles (and only the turbulence dispersion model is taken into account by default, but not crossing trajectory effects). Since this model uses volume statistics, is use forces their activation even if not otherwise requested (see idstnt).

◆ n_stat_classes

int n_stat_classes

◆ n_temperature_layers

int n_temperature_layers

◆ n_user_variables

int n_user_variables

◆ physical_model

int physical_model

activates (>0) or deactivates (=0) the physical models associated to the particles:

  • CS_LAGR_PHYS_HEAT: allows to associate with the particles evolution equations on their temperature (in degrees Celsius), their diameter and their mass
  • CS_LAGR_PHYS_COAL: the particles are pulverised coal particles. Evolution equations on temperature (in degree Celsius), mass of reactive coal, mass of char and diameter of the shrinking core are associated with the particles. This option is available only if the continuous phase represents a pulverised coal flame.

◆ precipitation

int precipitation

◆ resuspension

int resuspension
  • 0: no resuspension model
  • 1: resuspension model

◆ roughness

int roughness
  • 0: no DLVO conditions with roughness surface
  • 1: DLVO conditions with roughness surface

◆ shape

int shape
  • 0: spherical particles (default)
  • 1: spheroid particles
  • 2: ellipsoids

◆ viscous_terms

bool viscous_terms

Take viscous terms into account
