about 'matlab function' using refprom to get properties of methane

Hi there,

I want to link REFPROP with Simulink for methane. The pressure and temperature of the working fluid change. I want to import the fluid properties to Simulink, considering the changing pressure and temperature. Is it possible, and how can I do that?

Hi @闫,

To link REFPROP with Simulink, you will first need to link REFPROP with MATLAB, following the steps mentioned in the documentation from NIST or from Github:

https://trc.nist.gov/refprop/LINKING/Linking.htm#MatLabApplications

https://github.com/usnistgov/REFPROP-wrappers/tree/master/wrappers/MATLAB

Following this, REFPROP can be used within Simulink by creating a MATLAB Function block which contains MATLAB code performing REFPROP operations. An example of this workflow can be found in the following MATLAB answers post:

Hope this helps!
