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

◆ dlvo

int dlvo

◆ fouling

int fouling

◆ fragmentation

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

◆ idiffl

int idiffl

idiffl=1 suppresses the crossing trajectory effect, making turbulent dispersion for the particles identical to the turbulent diffusion of fluid particles. Useful if idistu=1

◆ idirla

int idirla

direction (1=x, 2=y, 3=z) of the complete model. It corresponds to the mean relative directions of the flow. Useful only if modcpl > 0 0 proposes an isotropic Lagrangian timescale. 4 proposes the local mean direction.

◆ idistu

int idistu

activation (=1) or not (=0) of the particle turbulent dispersion. The turbulent dispersion is compatible only with the RANS turbulent models ( $k-\varepsilon$, $R_{ij}-\varepsilon$, v2f or $k-\omega$). (iturb=20, 21, 30, 31, 50 or 60).

◆ modcpl

int modcpl

activates (>0) or not (=0) the complete turbulent dispersion model. When modcpl is strictly positive, its value is interpreted as the absolute Lagrangian time step number (including restarts) after which the complete model is applied. Since the complete model uses volume statistics, this is only effective once the time step reaches 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
