Detailed Description

Freestream velocity condition to be used in conjunction with the single rotating frame (SRF) model (see: SRFModel class)

Velocity condition to be used in conjunction with the single rotating frame (SRF) model (see: SRFModel class)

Given the free stream velocity in the absolute frame, the condition applies the appropriate rotation transformation in time and space to determine the local velocity using:

\[ U_p = cos(\theta)*U_{Inf} + sin(theta) (n^UInf) - U_{p,srf} \]

where

$ U_p = patch velocity [m/s]$ =
$ U_{Inf} = free stream velocity in the absolute frame [m/s]$ =
$ theta = swept angle [rad]$ =
$ n = axis direction of the SRF$ =
$ U_{p,srf} = SRF velocity of the patch$ =


Patch usage

Property Description Required Default value
UInf freestream velocity yes
relative UInf relative to the SRF? no

Example of the boundary condition specification:

    myPatch
    {
        type            SRFFreestreamVelocity;
        UInf            uniform (0 0 0);
        relative        no;
        value           uniform (0 0 0);    // initial value
    }

Given the free stream velocity in the absolute frame, the condition applies the appropriate rotation transformation in time and space to determine the local velocity.

The optional relative flag switches the behaviour of the patch such that:

  • relative = yes: inlet velocity applied 'as is':

\[ U_p = U_{in} \]

  • relative = no : SRF velocity is subtracted from the inlet velocity:

\[ U_p = U_{in} - U_{p,srf} \]

where

$ U_p = patch velocity [m/s]$ =
$ U_{in} = user-specified inlet velocity$ =
$ U_{p,srf} = SRF velocity$ =


Patch usage

Property Description Required Default value
inletValue inlet velocity yes
relative inletValue relative motion to the SRF? yes

Example of the boundary condition specification:

    myPatch
    {
        type            SRFVelocity;
        inletValue      uniform (0 0 0);
        relative        yes;
        value           uniform (0 0 0);    // initial value
    }
