摘要

建立了LNG螺旋缠绕塔压力损失计算模型。该模型采用三流方案:两个倾斜涡流在管壁间空间，由沿柱轴线的中心流分开。基于积分动量平衡定理，推导了液压阻力系数的计算公式。为了验证计算模型的结果，建立了实验装置并进行了实验。用该模型计算的水力阻力系数与实测实验数据比较，结果吻合较好。

Model of the Hydraulic Resistance for the Flow in a Spiral Wounded Column

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.
