I have followed a tutorial in Simscale and also a similar project in Forum.
The BCs for inlet are given as velocity inlet and outlet as pressure outlet with 0 Pa(g) mean pressure.
The outputs show unrealistic pressure values at inlets and outlets.
From basic reasoning I have used the following and got more realistic pressures.
- Inlet-Pressure inlet (e.g 0 Pa(g) mean pressure
- Outlet- Velocity outlet (with realistic velocity)
Once we fix the inlet pressure, the outlet pressure will be determined from energy and momentum considerations by CFD solution.
Any thoughts ?
