摘要

建立了液化天然气塔螺旋管内液体湍流膜流换热系数的简化模型。液体的重量和由于蒸汽流动而产生的摩擦力被考虑在内。将模型计算的换热系数与Fredheim论文的实验数据进行了比较。计算结果与实验结果吻合较好。

Calculation of Heat Transfer Coefficients in LNG Column

A simplified model of the heat transfer coefficient in a turbulent film flow of liquid flowing down the spiral tubes of an LNG column is developed. The weight of the liquid and the friction force due to the vapour flow are taken into account. The heat transfer coefficients calculated from the model are compared with the experimental data obtained in Fredheim’s thesis. A good agreement between the calculated and experimental data is obtained.

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
