Dear Foamers

I am trying to simulate a swirl flame and this flame has a primary (axial) air stream where-of swirl is induced aerodynamically.

This stream has distinct bulk axial and tangential mean velocities i.e. Us and Ws respectively.

I am going to set swirlFlowRateInletVelocity with includes:

Code:
 type          swirlFlowRateInletVelocity;
        flowRate        -------;
        rpm              -------; 
        value            uniform (0 0 0);
I have a doubt that causes me to ask this question:

In the above B.C. flowrate is computed via axial Bulk velocity
and rpm is computed through tangential velocity. Am I right?

Is it right to say that tangential velocity does not have contribution to the flowRate quantity in swirlFlowRateInletVelocity B.C. ?
Or tangential velocity affects the flowRate?


Regards
Bobi
