Abstract
A model for calculating pressure losses in a spiral wound LNG column has been developed. The model uses the scheme of three flows: two inclined vortex flows in the wall inter-tube spaces, separated by the central flow along the axis of the column. Based on the integral momentum balance theorem, a formula for the hydraulic drag coefficient was derived. To verify the results of the computational model, an experimental setup was built and experiments were conducted. Comparison of the calculations of the hydraulic resistance coefficient according to the model with the measured experimental data shows good agreement.
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.
