scalarTransportModel_generalManual command

Syntax

Defined in scalarTransportProperties dictionary.

}
  • phiName = (optional) name of the surface field for the SUPERFICIAL flux, default “phi”.
  • voidfractionName = (optional) name of the finite volume voidfraction field, default “voidfraction”.
  • scalar1 = (optional, default 0.7) turbulent Schmidt Nr, set to large value to suppress turbulent species transport
  • scalar2 = (optional, default 0.7) turbulent Prandtl Nr, set to large value to suppress turbulent heat transport
  • scalar3 = (optional, alternatively define word1) volumetric heat capacity as a global constant (in contrast to cpVolumetricFieldName for a field). This is the mixture density times the heat capacity J/K/(m_voidspace)^3, will only be used if cpVolumetricFieldName, or updateMixtureProperties = false
  • word1 = (optional, alternatively define scalar3) volumetric heat capacity as a field
  • word3 = mixture density field
  • C = concentration field name
  • T = temperature field name

Description

Solves the advection-dispersion transport equation for a dilute scalar quantity in the fluid phase. fvOptions can be specified to model sources, etc. in the fluid phase. Exchange models with a particle phase can be included by including appropriate forceModels in couplingProperties.

Restrictions

The user MUST ensure the “phi” field is SUPERFICIAL (i.e., the fluid-phase velocity times voidfraction interpolatedat the cells’ faces). The code cannot know or check whether this is the case, so the user of a certain solver has to ensure this.
