摘要

利用三维欧拉-欧拉模型对浆氢在水平圆管中的流动特性进行了数值模拟研究

通过数值计算确定了合适的颗粒-颗粒碰撞恢复系数、颗粒-壁面碰撞系数等相关参数

并将数值模拟的压降结果与文献中实验数据进行了对比。利用两相模型对固相体积分数分别为10%、20%、30%

流速分别为1 m·s-1、2 m·s-1、3 m·s-1

管道直径分别为10 mm、16.6 mm、23 mm下的浆氢流动特性进行了模拟

得到了浆氢的固相体积分数在管道截面上的分布

发现在较低流速、较低固相平均体积分数和较大管道直径的情况下固相颗粒的体积分数分布不均匀性更大。

Abstract

The flow characteristics of slush hydrogen in horizontal pipes are investigated numerically using 3D Euler-Euler model. The pressure drops obtained by the numerical calculation are compared with experimental results from the open literature

in order to validate the numerical method. In addition

the models with proper parameters are adopted to simulate the flow of slush hydrogen with different volume fractions (10%

20%

30%) and flow rates (1.0 m·s-1

2.0 m·s-1

3.0 m·s-1) in horizontal pipes with different diameters (10 mm

16.6 mm

23 mm). The volume fraction distributions of slush hydrogen in the pipe are obtained. It is found that the solid volume fraction distribution of slush hydrogen is more heterogeneous at lower flow rate

lower average volume fraction and larger pipe diameter.
