基于FLUENT的压力管道内部流场分析

摘要

针对压力管道，利用计算流体动力学软件 FLUENT，对其内部流场进行了数值模拟，得到了管道内部合理的压力场分布。通过对比三种不同直径的压力管道，得到了管道直径对其内部压力场影响的变化规律；同时本文探索了温度对管道内部流场变化规律的影响，为今后压力管道的设计和使用提供了一定的借鉴作用。%The flow field in pressure pipeline was numerically simulated by computational fluid dynamics software FLUENT, a reasonable pressure field distribution was obtained. By comparing pressure field distributions of three different diameter pressure pipelines, effect of pipeline diameter on the pressure field was obtained; At the same time, influence of temperature on the flow field in the pipeline was investigated, which could provide the reference for use and design of pressure pipelines in the future.
