So I downloaded coolprop-code from https://github.com/ibell/coolprop and compile the matlab wrapper present on that distribution. By doing that, I did compile the old 4.2.6 coolprop version. I understand that mixture syntax is not available in such an old version. The not working matlab instruction in case of 4.2.6 wrapper is: I just downloaded the R513A.MIX file for REFPROP and placed it in the mixtures folder. The mixture can be used from within REFPROP itself without problems, but when i try to use it through CoolProp, from Matlab it fails: How can I fix running a code that requires air Learn more about matlab, refprop Welcome to REFPROP CAPE-OPEN.

Mixture calculations 2017-08-04 For a mixture, it contains the names of the constituents in the mixture separated by semicolons or asterisks. Once the routine has been called with hFld set to the desired fluids, a space can be sent for all other calls that use the same fluid(s). For a predefined mixture, the extension “.mix” must be included. 2019-06-12 I encountered a problem when calling Refprop software using Matlab.

The more complex features (like user-defined mixtures) seem to be rather problematic. 2019-08-03 How to calculate mixture thermodynamic properties in 2-phase state in Refprop? I want to calculate thermodynamic properties of Ammonia-water mixture at some specific points in Refprop. REFPROP is based on the most accurate pure ﬂuid and mixture models currently available.

For REFPROP and HEOS backends, it's always molar fractions. For incompressible, it depends.

thank you. 5 Comments. 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.

Please note carefully that the 79/21 N2/O2 mixture is not meant for air calculations, but as a teaching tool to study composition changes as the mixture passes through the two phase.

REFPROP, and therefore the REFPROPFlowStation, runs fast if the composition is set to a pure fluid or a pseudo-pure fluid. However, execution speed slows when composition comprises multiple fluids, whether set via a predefined mixture file (".mix" extension) or defined manually via the FlowStation comp attribute. 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.
