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.

螺旋损伤柱流动的水力阻力模型

摘要

已经开发出计算螺旋缠绕式液化天然气塔中压力损失的模型。该模型采用三流方案：壁管间空间中的两个倾斜涡流，由沿柱轴的中心流分开。根据积分动量平衡定理，推导了水力阻力系数的计算公式。为了验证计算模型的结果，搭建了实验装置并进行了实验。将模型计算的水力阻力系数与实测实验数据进行比较，结果吻合良好。
