Abstract

Automated information systems were considered which provide users of data on thermophysical properties of fluids. An automated system for calculating the thermophysical properties of cryogenic fluids, refrigerants and their mixtures in gaseous and liquid states, developed by authors of paper, has been described. It allows the calculation of compressibility factor, density, enthalpy, entropy, isochoric and isobaric specific heats, speed of sound, Joule-Thomson coefficient, viscosity, thermal conductivity, and some other properties. These properties can be determined in the single-phase and two-phase regions and on the phase-equilibrium lines at temperature from the triple point up to 400…1500 K and at pressure 35…100 MPa for twelve combinations of independent variables.
