matchedFlowRateOutletVelocity

Description

The matchedFlowRateOutletVelocity is a velocity-outlet boundary condition that corrects the extrapolated velocity to match the flow rate of the specified corresponding inlet patch.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            matchedFlowRateOutletVelocity;

    // Optional entries
    inletPatch      <word>;
    rho             <word>;
    volumetric      <bool>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: matchedFlowRateOutletVelocity	word	yes	-
inletPatch	Name of patch from which the corresponding flow rate is obtained	word	yes	-
rho	Name of the density field used to normalize the mass flux	word	no	rho
volumetric	Flag to enable volumetric- (true) of mass-based flow rate	bool	no	true
