WCNSFV2PSlipVelocityFunctorMaterial
This material computes the slip velocity between a dispersed phase and a mixture phase. The slip velocity is modeled as follows:
where:
is the particle relaxation time,
is the linear drag coefficient function,
is the density of the dispersed phase,
is the density of the mixture,
is the acceleration vector.
The particle relaxation time is modeled as follows Bilicki and Kestin (1990):
where:
is the particle diameter,
is the mixture dynamic viscosity.
The acceleration vector is the particle acceleration vector:
where:
is the acceleration of gravity,
is the volumetric force,
is the mixture velocity.
