摘　　要：为研究深冷惰气浆液在水平管道输送过程中的压力损失,基于固液俩相流理论,运用Fluent软件对不同初始速度,不同固相颗粒体积分数,不同固相颗粒粒径的浆液在水平管道输送过程中的压力损失进行数值模拟研究。结果显示,随着初始流速的增大,浆液在水平管道输送过程中的压力损失增大,干冰体积分数增大,压力损失增大,干冰颗粒粒径增大,压力损失减小。In order to study the pressure loss of cryogenic inert gas slurry during horizontal pipeline transportation,based on the theory of solid-liquid two-phase flow,Fluent software is used to analyze the slurry with different initial speeds,different solid phase volume fractions,and different solid phase particle sizesNumerical simulation of pressure loss during horizontal pipeline transportation.The results show that with the increase of the initial flow velocity,the pressure loss of the slurry during the horizontal pipeline transportation increases.As the volume fraction of the solid phase increases,the pressure loss increases.As the particle size of the solid phase increases,Pressure loss is reduced.
