how to use refprop with mixtures. Learn more about refprop mixture Simscape. Skip to content. MATLAB Answers. Here we are going to understand 1.
The substance can be a pure fluid such as R-134a or a predefined mixture such as R-404a, a ternary mixture of R-125, R-143a, and R-134a. The database can be REFPROP, an industry standard developed by NIST, or the open-source CoolProp. The tables are stored in fluidTables as a structure array. accessing the REFPROP DLL or the FORTRAN property subroutines. REFPROP is based on the most accurate pure fluid and mixture models currently available. It implements three models for the thermodynamic properties of pure fluids: equations of state explicit in Helmholtz energy, In this code "result = refpropm (prop_req, spec1, value1, spec2, value2, material1)", the first or second input character (spec1 or spec2) does not seem to support the vector input. As we all know, Mixture composition may be set on a mass basis using ".fld" files as follows.

The database can be REFPROP, an industry standard developed by NIST, or the open-source CoolProp. The tables are stored in fluidTables as a structure array. A surprising number of people on RG have tried to link Refprop to MATLAB with varying success. The more complex features (like user-defined mixtures) seem to be rather problematic. t5 = 6+273; %in kelvin. p5 = refpropm ('P','T',t5,'Q',1,'r407c.mix'); h5 = refpropm ('H','T',t5,'P',p5,'r407c.mix'); s5 = refpropm ('S','T',t5,'P',p5,'r407c.mix'); but i got some error, said that; Error using refpropm (line 267) [SETUP error 101] error in opening file for component #-22; filename = (C:\Program Files.
In the model you want to Import the Mixture to, simply open the System Properties window, choose NIST REFPROP …
