The static inlet pressure varies with the diameter of the nozzle throat from 100,000 up to 500,000 Pa. Could it be that the inlet pressure I set is the total pressure?
If that’s the case and I don’t know the inlet speed, how am I supposed to determine the correct total pressure for different geometries? The volumetric flow rate and thus the speed, changes depending on the nozzle shape, so I can’t predict which flow rate will prevail at each simulation.
Additionally, my simulation hasn't converged either. I have set the residuals to 1e-6 for convergence.
