Detailed Description

This boundary condition provides a velocity boundary condition for multphase flow based on a user-specified volumetric flow rate.

The flow rate is made proportional to the phase fraction alpha at each face of the patch and alpha is ensured to be bound between 0 and 1.

Usage
Property Description Required Default value
flowRate volumetric flow rate [m3/s] yes
alpha phase-fraction field yes

Example of the boundary condition specification: 

    <patchName>
    {
        type            variableHeightFlowRateInletVelocity;
        flowRate        0.2;
        alpha           alpha.water;
        value           uniform (0 0 0); // placeholder
    }

The flowRate entry is a Function1 of time, see Foam::Function1Types.

Note
  • the value is positive into the domain
  • may not work correctly for transonic inlets
  • strange behaviour with potentialFoam since the momentum equation is not solved
