EQUATION OF STATE AND THERMOPHYSICAL PROPERTIES OF HELIUM-3
Yonghua Huang, G.B. Chen, V. Arp, Ray Radebaugh
Experimental data of the thermophysical properties of 3He were mined into a searchable database. Equilibrium nist-equations along the vapor-liquid and liquid-solid lines were proposed. A general nist-equation of state for normal fluid 3He based on the Debye specific heat model was developed. Calculations by the Debye fluid 3He state nist-equation differ from the reference experimental data generally within +/-1% for the p-v-T, +/-0.9% for the specific heat and +/-1% for the velocity of sound. A graphical computer program was developed to simplify the calculation of 3He properties in a wide range for temperature from 0.01 K to 300 K and pressures up to 15 MPa. 3He T-s and p-h diagrams were plotted.
