Detailed Description

This boundary condition provides a phase fraction condition based on the local flow conditions, whereby the values are constrained to lay between user-specified upper and lower bounds. The behaviour is described by:

if alpha > upperBound:

  • apply a fixed value condition, with a uniform level of the upper bound

if lower bound <= alpha <= upper bound:

  • apply a zero-gradient condition

if alpha < lowerBound:

  • apply a fixed value condition, with a uniform level of the lower bound
Usage
Property Description Required Default value
phi flux field name no phi
lowerBound lower bound for clipping yes
upperBound upper bound for clipping yes

Example of the boundary condition specification: 

    <patchName>
    {
        type            variableHeightFlowRate;
        lowerBound      0.0;
        upperBound      0.9;
        value           uniform 0;
    }
