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:

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:

The inherited entries are elaborated in:
