I am having an Refprop error 203,tprho(density) when i try to use hybrid initialization.
My simulation is as follows for a Ejector 2D axi-symmetric model using k-omega SST. Working Fluid: R134a superheated vapour using real gas properties in NIST a) (Pressure-inlet) Inlet Motive Pressure = 28 Mpa and T = 357.4k b) (Pressure-inlet) Inlet Entrained Pressure = 4Mpa and T = 283k c) (Pressure-outlet) Outlet Pressure = 8.3Mpa and T = 303.5k My guess is that there are problems with the Boundary Conditions. However, i ensured that my B.C. are in the bounded range provided by NIST database. |

Have you tried standard initialization?

Can i ask what is the fundamental difference between std and hybrid intialization?
