INSFVScalarFieldAdvection
This object adds a term for an arbitrary scalar field , where corresponds to the nonlinear variable that this kernel acts on. The nonlinear variable can be of type MooseVariableFVReal or for consistency with other INSFV naming conventions, can be of type INSFVScalarFieldVariable.
When using a mixture model for multiphase flows, this kernel also allows us to add the slip velocity, which is modeled by the following term:
where:
is the slip velocity of the transported phase
When adding the slip velocity, the net advection term that is added is the following , where is the mixture velocity.
