SRFWallVelocity

Description

The SRFWallVelocity is a boundary condition that provides wall-velocity condition to be used in conjunction with the single rotating frame (SRF) model.

The condition applies the appropriate rotation transformation in time and space to determine the local SRF velocity of the wall.

$$\u_p = - \u_{p,srf}$$

where:

Property	Description
$\u_p$	Patch velocity [m/s]
$\u_{p,srf}$	SRF velocity

The normal component of $\u_p$ is removed to ensure zero wall-flux even if the wall patch faces are irregular.

Usage

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

Boundary file

<patchName>
{
    type            wall;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            SRFWallVelocity;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: SRFWallVelocity	word	yes	-

The inherited entries are elaborated in:
