Welcome to REFPROP CAPE-OPEN. Welcome to REFPROP CAPE-OPEN. This program provides a CAPE-OPEN versions 1.0 and 1.1 interface to NIST's REFPROP application. For this program to work, a separate installation of NIST's REFPROP version 8 or later must be present on your system. For more information about REFPROP, see the NIST web site. What CAPE-OPEN?

MATLAB is an awful(!) environment for calling shared libraries (DLL) or C++ code. Calculate properties in Matlab. From Matlab command line you can call the methods in Prode Properties by typing the names, for example to calculate cp/cv at specified conditions >> EstrGCp(1,300,500000)/EstrGCv(1,300,500000) >> ans = 1.3211 or, to calculate the speed of sound for vapor phase at same conditions >> EstrGSS(1,300,500000) >> ans = 374.1625 It contains a limited number of pure fluids (water, CO2, R134a, nitrogen, oxygen, methane, propane, helium, hydrogen, and dodecane), along with air as a pseudo-pure fluid. It also allows mixture calculations of a 50/50 molar mix of nitrogen and methane or of a 79/21 molar mix of nitrogen and oxygen for teaching vapor-liquid equilibrium (VLE). The ammonia-water mixture flowing into the absorber is assumed to be a mixture of the dilute solution flowing out of the absorber (saturated liquid, x sol = 0.3, P sol = 500 kPa, and m ˙ sol = 3 g s-1) and refrigerant vapor from the evaporator (saturated vapor, y ref = 0.999, P ref = 500 kPa, refrigerant flow rates vary with time in the simulation, so m ˙ ref ≈ 1 g s-1). As the two-phase ammonia-water mixture flowing through the absorber has substantial variations in density, the exact 1 C3H8Tables = twoPhaseFluidTables([-195,800],[0.00001,10],50,50,150, 'R401A', 'C:\Program Files (x86)\REFPROP') fails to find the mixture file R401A.MIX There is a file int eh REFPROP/MIXTURE folder labled R401A.MIX 2019-03-22 Define New Mixture¶.

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. 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, the modified Benedict-Webb-Rubin equation of state, and an extended corresponding states (ECS) model.
