Prediction of the Conductivity of O-H2 and P-H2 Based on the Quantum Law of Corresponding States
Based on the quantum law of corresponding states and considering the structural differ-ences between hydrogen isomers,a mathematical model was developed for predicting the transport parameters of low-temperature orthohydrogen and parahydrogen.The results were examined and analyzed,and it was found that the quantum correspondence state principle method could predict the viscosity and thermal conductivity of orthohydrogen and parahydrogen in the temperature range of 20～100 K and pressure range of 0.01～10 MPa with good accuracy.The pressure has a significant impact on the prediction accuracy of the model,and the prediction error of the correspondence state principle is basically controlled within 6％when the ambient pressure is less than 1 MPa.Further correction of the physical constants in the model is expected to improve the prediction accuracy of the correspondence state principle.
