Description

The interstitialInletVelocity is a velocity boundary condition with which the actual interstitial velocity is calculated by dividing the specified inletVelocity field with the local phase-fraction.

Usage

The condition requires entries in both the boundary and field files.

Boundary file 

<patchName>
{
    type            patch;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type                interstitialInletVelocity;
    inletVelocity       <vectorField>;
    alpha               <word>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
type Type name: interstitialInletVelocity word yes -
inletVelocity Non-interstitial inlet velocity vectorField yes -
alpha Name of the phase-fraction field word yes -
