摘　　要：利用三维粒子动态分析仪，对一单总管排气系统始端模件稳态湍流流场进行了准三维测量，并用ALE法对其流场进行了三维数值模拟。计算结果与试验结果吻合良好，反映了模件流场的三维特征。The three dimensional particle dynamic analyzer has been used to do the quasi - threedimensional measurement on the steady tUrbulent flow field in the closed junction module of single Plenumexhaust system and the three dimensional numerical simulation on the flow field has been performed by us-ing the ALE method. The calculated results have a good agreement with the measured ones, which indicates the three dimensional feature of the module flow field.
