![]() With a considerable simplification of the installation routine, the inclusion of 1-Hexene and the further low-GWP refrigerants R1224yd(Z), R1233zd(E), R1234ze(Z), R1243zf, R1336mzz(Z), R1336mzz(E), the most recent update of R1234yf, the transport properties on the phase boundary for R1224yd(Z) and R1336mzz(E) and the transport properties for R1233zd(E) and Propylene Glycol, the version level of FluidCal was last increased to version 2.3.2.5.Ĭalculation of the thermodynamic properties of refrigerants R1224yd(Z), R1233zd(E), R1234yf (new 2022), R1234ze(E), R1234ze(Z), R1243zf, R1336mzz(Z) and R1336mzz(E ) In addition, the range of functions of FluidCal has been extended by the calculation of the surface tension for almost all substances integrated in FluidCal as well as the thermal diffusivity and Prandtl number for many substances. Ĭompared with the substance catalog of the widely used version 2.0.0.8 the software version of FluidCal has been increased to version 2.2.1.0 by the recent update of the equations of state for benzene, chlorine, hydrogen, hydrogen chloride, cyclohexane, cyclopentane, ethanol, ethylbenzene, helium, sulfur dioxide and 2,3 Dimethylbutane, the new inclusion of the equations of state for 1,2-dichloroethane, chloroethene (vinyl chloride), ethylene oxide, propylene glycol, methyl diethanolamine, 3-Methyl pentane, 2,2-Dimethylbutane, n ‑ Perfluorobutane, n ‑ Perfluoropentane, n ‑ Perfluorohexane, R1234ze(E) and the equations of state of hexamethyldisiloxane, octamethylcyclotetrasiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, dodecamethylpentasiloxane, tetradecamethylhexasiloxane, decamethylcyclopentasiloxane, which are particularly suitable for ORC processes. FluidCal is currently available for 96 substances, but will be continuously developed and can be expanded on demand at short notice. ![]() ![]() In order to offer a calculation software for as many substances as possible, the FluidCalsoftware package contains both the equations of state developed at the Chair of Thermodynamics of the Ruhr-University Bochum and equations by other authors. Equations of state for 96 substances covered by the Software FluidCal of version 2.3.2.5 NET DLL are given in Section 3 of this software description.ĭetailed information about the current distribution channel by the engineering office Dr.-Ing. Information about the use of the software under the various Windows operating systems and Excel versions as well as the integration of the available 32- bit or 64-bit Fortran DLL using Excel Add-Ins and 32-bit. All combinations of temperature T, pressure p, density ρ, specific enthalpy h, and specific entropy s can be selected as input variables for the calculations of thermodynamic properties. ![]() For more than 90 substances, the software enables the calculation of 17 thermodynamic properties, three partial derivatives and for a number of substances (see the list in Table 1) also the calculation of dynamic and kinematic viscosity, thermal conductivity, Prandtl number, thermal diffusity and surface tension. The program FluidCal was developed for the calculation of thermodynamic properties from equations of state (fundamental equations of state in the form of the Helmholtz free energy) in research and for technical applications.
