摘要
Abstract
Based on Missenard method that estimates liquid thermal conductivity under pressurization condition by look-up table, and using liquid thermal conductivity data in literature, a new calculation model for liquid thermal conductivity under pressure was obtained. The model was used to calculate the thermal conductivity for 18 liquid systems containing 313 data points under pressure. It shows that the overall average relative deviation between calculation and experiment is 3. 08% ; the calculation is satisfactory with experimental data; the accuracy of calculation is better than that in literature. The model is simple and convenient, and the liquid thermal conductivity under pressure and various temperatures can be immediately predicted merely by the critical temperature, critical pressure and thermal conductivity data at low pressure.关键词
