I am solving CHT for internal heat exchanger component. I am having 2 phases, viz., liquid & vapour phase. In liquid phase density is mainly depends on temperature only, but in vapour phase density is depends on both pressure and temperature. In fluent I modeled my vapour refrigerant as a fucntion of temperature only with constant pressure. Since I could not get proper result when compare with experimental values.

So far I tried with ideal gas and real gas models to formulate density. It is also not giving proper result.

Kindly give your suggestions to model my vapour refrigerant.
