This option adds transport terms into the equations to account for the presence of a constant volume fraction. The volume fraction is read from constant/alpha.<phase>, where <phase> is given as a parameter to the option. 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 option adds transport terms into the equations to account for the presence of a constant volume fraction. The volume fraction is read from constant/alpha.<phase>, where <phase> is given as a parameter to the option. 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
`phase`	Name of the phase associated with the volume fraction	yes
`phi`	Name of the flux field	no	phi
`rho`	Name of the density field	no	rho
`U`	Name of the velocity field	no	U
`fields`	Names of the fields to apply the option to	yes

Example specification:

    <fvOptionName>
    {
        type        volumeFractionSource;
        phase       solid;
        phi         phi;
        rho         rho;
        U           U;
        fields      (rho U e);
    }
