Keywords derived from modele_turbulence_scal_base

Keywords introduced by TrioCFD that extend the Modele_turbulence_scal_base family. See Keywords derived from modele_turbulence_scal_base for the base-class documentation and the canonical keyword list.


sous_maille_dyn

Dynamic sub-grid turbulence modele.

Warning : Available in VDF only. Not coded in VEF yet.

Parameters:

  • [stabilise] (type: string into ['6_points', 'moy_euler', 'plans_paralleles']) not_set
  • [nb_points] (type: int) not_set
  • [dt_impr_nusselt] (type: float) Keyword to print local values of Nusselt number and temperature near a wall during a turbulent calculation. The values will be printed in the _Nusselt.face file each dt_impr_nusselt time period. The local Nusselt expression is as follows : Nu = ((lambda+lambda_t)/lambda)*d_wall/d_eq where d_wall is the distance from the first mesh to the wall and d_eq is given by the wall law. This option also gives the value of d_eq and h = (lambda+lambda_t)/d_eq and the fluid temperature of the first mesh near the wall. For the Neumann boundary conditions (flux_impose), the <<equivalent>> wall temperature given by the wall law is also printed (Tparoi equiv.) preceded for VEF calculation by the edge temperature <<T face de bord>>.
  • [dt_impr_nusselt_mean_only] (type: dt_impr_nusselt_mean_only) This keyword is used to print the mean values of Nusselt ( obtained with the wall laws) on each boundary, into a file named datafile_ProblemName_nusselt_mean_only.out. periode refers to the printing period, this value is expressed in seconds. If you don\'t use the optional keyword boundaries, all the boundaries will be considered. If you use it, you must specify nb_boundaries which is the number of boundaries on which you want to calculate the mean values, then you have to specify their names.
  • [turbulence_paroi] (type: turbulence_paroi_scalaire_base) Keyword to set the wall law.
