rotatingPressureInletOutletVelocity

Description

The rotatingPressureInletOutletVelocity is a velocity inlet/outlet boundary condition that applies a zero-gradient condition for outflow (as defined by the flux); and obtains velocity from the flux with a direction normal to the patch faces. The condition is applied to patches in a rotating frame where the pressure is specified.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            rotatingPressureInletOutletVelocity;
    omega           <Function1<vector>>;

    // Inherited entries;
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: rotatingPressureInletOutletVelocity	word	yes	-
oemga	Angular velocity of the frame [rad/s]	Function1<vector>	yes	-

The inherited entries are elaborated in:

• Foam::pressureInletOutletVelocityFvPatchVectorField
• Foam::Function1

• Sign conventions:
  • positive flux (out of domain): apply zero-gradient condition
  • negative flux (into of domain): derive from the flux with specified

direction
