volumeFractionSource Class Reference

This fvModel adds transport terms into the equations to account for the presence of a constant volume fraction. The volume fraction is read from constant/alpha.<volumePhase>, where <volumePhase> is given as a parameter to the fvModel. Both advective and diffusive terms are added, and the resulting solution is time-accurate. The flux and velocity are treated as superficial. More...

Detailed Description

This fvModel adds transport terms into the equations to account for the presence of a constant volume fraction. The volume fraction is read from constant/alpha.<volumePhase>, where <volumePhase> is given as a parameter to the fvModel. Both advective and diffusive terms are added, and the resulting solution is time-accurate. The flux and velocity are treated as superficial.

This can be used to represent the effect of porous media that are caused purely by the reduction in volume of the fluid phase; i.e., additional blockage, and changes to transport and diffusion rates. It does not represent losses or transfers with the porous media. That requires separate sub-modelling.

Usage
Property Description Req'd? Default
phi Name of the flux field no phi
