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.
