LinearWCNSFV2PMomentumDriftFlux

This object implements the contribution to the momentum equation from the drift flux term in the linear finite volume discretization.

The user can set the slip velocity from their specific calculations. However, we recommend the usage of WCNSFV2PSlipVelocityFunctorMaterial for computing the slip velocity.

This term can be interpreted as the extra convection that is added due to the particles being transported in the flow field.

note

If the mixture model is used to capture more than one dispersed phase, a different LinearWCNSFV2PMomentumDriftFlux kernel should be added for each of the transported phases with the corresponding slip velocity for each phase.

note

Because the mixture density is computed inside LinearWCNSFV2PMomentumDriftFlux, this kernel is not compatible with mixture fluid properties in the fluid properties module that do not use a linear volume mixing for densities.
