Fundamental Equations of State for Parahydrogen, Normal Hydrogen, and Orthohydrogen
J. W. Leachman, R. T Jacobsen, and S. G. Penoncello
New fundamental equations of state for parahydrogen, normal hydrogen, and orthohydrogen were developed to replace the existing property models. To accurately predict thermophysical properties near the critical region and in liquid states, the quantum law of corresponding states was applied to improve the normal hydrogen and orthohydrogen formulations in the absence of available experimental data.
