using RGP to simulating the Non-equilibrium Phase Change

zijinzh · March 15, 2020, 02:57

When I set my Non-equilibrium Phase Change sinulation using a gas rgp file and a liquid file. The cfx remind me this error. I think that the homogeneous Binary Mixture was used in equilibrium Phase Change simulation, but I couldn't find the way to set the Fluid Pair editor. Could you tell me what I should do?

This is the error.

In Analysis 'Flow Analysis 1' - Domain 'R1': The Thermal Phase Change model has been activated for the fluid pair 'G | L', but the Saturation Temperature details have not been specified. These must be defined in either the Fluid Pair editor or in the definition of a Homogeneous Binary Mixture.

Doesn't the error message tell you exactly what is wrong? You need to set a saturation temperature.

but I can't find where the saturation temperature was set

Here's a quote of the error message "These must be defined in either the Fluid Pair editor or in the definition of a Homogeneous Binary Mixture."
