What velocity Boundary condition to use With Total Temperature and Pressure

Hello Foamers,

I'm a bit confused with the boundary conditions for a total Pressure and Temperature Inlet. The solver being used in buyoantSimpleFoam, I've defined T and P_rgh as:

Code:

P_rgh

{

      Inlet { type prghTotalPressure;   p0 uniform 101325; gamma 1.4;}

}



T

{

      Inlet { type totalTemperature;     T0 293.7; gamma 1.4; }

}

for U, I'm not sure what velocity condition to use. the "pressureDirectedInletOutletVelocity" condition seems to have been designed to work with a TotalPressure condition, but is it suited for the prghTotalPressure?

Thank you!
