| Abstract: | 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. |
