摘要:: 煤层气开发过程中，微细的颗粒随气流进入集输管网。颗粒的存在使管流形成气固两相流动，影响管路特性。采用模拟软件针对直管段及水平弯管进行气固两相流数值模拟，对管道系统的特性、操作条件和物料性质等影响气固两相流压力损失的主要因素进行了探讨，对连续相速度和压力分布特性以及颗粒运动轨迹进行了分析，得到气固两相流动的压力场、速度场分布，颗粒在管内的分布情况和运动轨迹，以及不同工况条件下的系统阻力和颗粒沉积分布规律，并结合煤层气现场含尘情况进行了数值模拟分析，结果表明：煤层气管道管流属于低浓度气固两相流，与纯气相单相流相比，颗粒引起的单位管长压降增幅低于2%。

Abstract:: During the development of Coal Bed Methane(CBM),very small particles will enter into the gathering pipe network with gas flow.The existence of particles will result in gas-solid two-phase flow in the pipe,which will affect the pipe characteristics.Gas-solid two-phase flow numerical simulation for the straight pipe and horizontal elbow is conducted with software,the main factors affecting the pressure loss of gas-solid two-phase flow including pipe system characteristics, operation conditions and properties of material are discussed and the speed and pressure distribution characteristics of continuous phase and particle motion trajectory are analyzed.The distribution of pressure field and velocity field of gas-solid two-phase flow and the distribution of particles in pipe and their motion trajectory are obtained as well as the systematic resistance and sedimentation distribution law of particles under different working conditions.This paper carries out numerical simulation analysis according to the dust in CBM pipe on the spot and the result shows that the flow of CBM pipe belongs to low concentration gas-solid two-phase flow and the increase in pressure drop amplitude per pipe length caused by the particles is lower than 2%compared with pure gas phase flow.(7 Figures,1 Table,12 References)
