Thermodynamic and Transport Properties of Cryogenic Propellants and Related Fluids

Abstract

Significant advances have been made in recent years in the quality and range of thermophysical data for the cryogenic propellants, pressurants, and inertants. These advances have resulted from improved evaluation and compilation techniques coupled with better and more extensive experimental data and from a better theoretical understanding of the physical properties of gases. A review of recently completed and current data compilation projects for helium, hydrogen, argon, nitrogen, oxygen, fluorine, and methane will be given as well as recommended references for thermodynamic and transport property data tables for these fluids. Modern techniques in the plotting of thermodynamic charts from tabular data (or from functions such as the equation of state) have greatly improved their precision and value. A list of such charts is included.
