Cryogenic fluids thermophysical properties

NISTELUIDS NIST STN programs for calculating thermophysical and transport properties of cryogenic fluids... 

The values in these tables were generated from the NIST REFPROP software (Lemmon, E.W., McLinden, M.O., and Huber, M.L., NIST Standard Reference Database 23 Reference Fluid Thermodynamic and Transport Properties—REFPROP, National Institute of Standards and Technology, Standard Reference Data Program, Gaithersburg, Md., 2002, Version 7.1). The primary source for the thermodynamic properties is McCarty, R.D., and Arp, V D., A New Wide Range Equation of State for Helium, Ado. Cryo. Eng. 35 1465-1475,1990. The source for viscosity is Arp, V. D., McCarty, R. D., and Friend, D. G., Thermophysical Properties of Helium-4 from 0.8 to 1500 K with Pressures to 2000 MPa, NIST Technical Note 1334, Boulder, Colo., 1998. The source for thermal conductivity is Hands, B. A., and Arp, V. D., A Correlation of Thermal Conductivity Data for Helium, Cryogenics, 21(12) 697-703,1981. 

For illustration. Figure 1.2 plots the temperature and pressure ranges over which the four fluids exist as liquids between the saturation curve and triple line. Temperature/ pressure (T/P) plots are used throughout the text to illustrate how the LAD performs as a function of the thermodynamic state of the liquid. For comparison. Table 1.1 lists the four primary cryogenic fluids along with thermophysical properties at the NBP saturation conditions relevant in the current work, such as the saturation temperature, heat of vaporization hfg, liquid density pf, kinematic viscosity v, and surface tension j lv- Clearly, advanced systems are required to store, maintain, and transfer such cold liquids.
