New Features of REFPROP Version 9.1
Enhancements have been made to most areas of the NIST REFPROP program, including the graphical interface, the Excel spreadsheet, the Fortran files (i.e., core property routines), the sample programs in C++, MatLab, VB, etc., and additional fluids. The number of enhancements has been substantial, with some of the more important ones listed below:
Convergence along the saturation lines is now much better and faster for complex mixtures due to new algorithms for finding phase boundaries, the addition of analytical derivatives in the calculation of the fugacity, and spline curves to provide initial inputs to the phase boundary routines.
The FORTRAN code was organized to be threadsafe and allow multi-core processing.
A 64-bit version of the DLL is available for use with Excel or Matlab.
The addition of the following fluids: cyclopentane, diethyl ether, ethylbenzene, hydrogen chloride, isooctane, m-xylene, Novec649, o-xylene, p-xylene, RE143a, R40, R1216, RE245cb2, RE245fa2, RE347mcc, R1233zd.
The equations of state have been revised for benzene, cyclohexane, deuterium, dimethyl carbonate, ethanol, helium, R161, and R1234ze.
Transport equations have been added or modified for many of the fluids, including: hydrogen, Novec649, parahydrogen, deuterium, isooctane, benzene, toluene, SO2, hexane, heptane, RE347mcc, R236fa, R236ea, R245fa, SF6, ethanol, water, and all of the siloxanes.
MatLab routines now use the Refprop DLL directly and can be directly modified.
Additional plots for analyzing equations of state are available.
