totalPressre in OpenFOAM
I want to compare a STAR-CD Simulation with OpenFOAM.
It's a simple incompressible flow through a duct.
In STAR you can define the inlet: total pressure p=75Pa.
So i used the totalPressure boundary condition in OpenFOAM:
p0 uniform 62.2406639;
value uniform 0;
because it's an incompressible flow i used p/density for the value p0.
75Pa/1.205 kg/m³ = 62.2406639 m²/s²
EnSight is used for the interpretation of the results.
Instead of the 62.2406639 there is an another, smaller value present at the inlet.
- Is a smaller value defined because of p=p0 - 0.5*U²
- Is it possible in OpenFOAM to define a total Pressure boundary condition with an
fixed Value (like in STAR-CD) ?
