摘　　要：在机械设计等工程实际中,管道的压力损失计算是其设计的一项非常重要的任务。为了确定某管道内置传感器的最佳插入点,就要计算因传感器而引起的管道流动损失,建立了不同设计的内置传感器管道的数学模型,使用目前通用的专业CFD数值计算软件FLUENT对管道内流场进行三维数值模拟,并将不同设计的计算结果进行对比分析,认为流动损失相对较小且流场流速稳定度较好的型4为最优设计,计算结果为该管道的进一步优化设计提供了参考。It is an important task to obtain the pipe pressuer loss in the engineer and mechanical design.To determine the best position of the sensors in a pipeline,the pressuer loss caused by the sensors must be computed.3D physical and mathematical model was built to simulate the flow in different designs by means of the widely used CFD software tool FLUENT,and the results of five designs were compared and analysed,the conclusion is that type 4 is the best design due to the lower pressuer loss and the stability of the the flow velocity,and the further optimization of the pipline is thrown light on.
