How Link NIST REFPROP WITH ANSYS FLUENT USING COMMANDS TO ADD THERMAL PROPERTIES?

atulsbhat · November 17, 2019, 10:18

I am Currently Working on Developing Correlations for SuperCritical Fluids for a rectangular Flat Plate. As I am New To ANSYS FLUENT , Can You Kindly Guide me How to Add, Thermophysical Properties of Supercritical Fluids (Cp, Rho, Viscosity and Thermal Conductivity), ISOBARIC 225 BAR, Varying With Respect to Temperature 630K to 670K. I do have access to To Nist REFPROP and I am Not Able to Hook it with ANSYS FLUENT.
Thank You

You don't need to hook it. REFPROP is integrated into Fluent already. To use it, type:

Code:

define/user-defined-real-gas-models/nist-real-gas-model

and then follow all the prompts

I Tried Doing This, But Wrong values of Cp Came and Density as Function of Temperature was Not Inputted. Density Error Came

Can You Kindly Guide me How to Add, Thermophysical Properties of Supercritical Fluids{H2O} (Cp, Rho, Viscosity and Thermal Conductivity), ISOBARIC 225 BAR, Varying With Respect to Temperature 630K to 670K. I do have access to To Nist REFPROP and I am Not Able to Hook it with ANSYS FLUENT. I am not able to add a pic here where i used commands and Failed.I can Mail U, If You provide me ur mail address.

BC: Velocity Inlet and Pressure Outlet, Pressure Based Solver, Parallel processing, Laminar

Have you solved this problem?

I am also working with ANSYS in simulating supercritical pressure fluids.
