Species Volume Expansion#
Species Volume Expansion = CONSTANT <species> <float> [1/T]
Description / Usage#
This card is used to specify the model for the coefficient of volume expansion associated with the concentration of a particular species. This property is optional for the BOUSS and BOUSSINESQ option on the Navier-Stokes Source card and, if nonzero, will result in a buoyancy term to be added to the Navier-Stokes equation that is apportioned to the species volume expansion coefficient, defined as the logarithmic sensitivity of density to concentration, or (dlnr) ⁄ (dC).
Name of the constant volume expansion coefficient model.
The following is a sample input card:
Species Volume Expansion = CONSTANT 0 0.
WARNING: Please be aware that if the thermal volume expansion coefficient is also nonzero, the buoyancy force will be augmented.
