Reply To: Convergence issues with NIST real gas modell at increasing velocity inlet

[Georgiy Tanasov]

There are some points in the domain where local velocity exceeds 100m/s and i wanted to account for compressibilty and just for good quality results, of course i could use another model but im just wondering why it happens. Inlet temp is 313K and wall temperatures are 299K. Amount of cells started wit 420k and i increased it gradually to 1,2M and no change of the behaviour, it was always the same point of 12,5ms where it diverged (12,4 still converged). Im studying pressure drop and hea transfer rate
