Hello everyone,
I am trying to implement a real-gas model for a CO2 ejector. My properties are interpolated from lookup tables, and this is working well for thermal conductivity, specific heat and viscosity. As for density, the simulation converges when I use an ideal-gas model; however, when I switch to my UDF, the simulation does not converge. Even if I write a UDF for density that replicates the ideal gas model, I have problems. I would appreciate any help. Thank you. |
