理想压力室模型中流场形态研究

The results of flow experiments performed in a cylinder array designed to mimica Next Generation Nuclear Plant lower plenum design are presented. Pressure drop and velocity field measurements are made. Based on these measurements, five regimes of behavior are identified that are found to depend on Reynolds number. It is found that the recirculation region behind the cylinders is shorter than that of half cylinders placed on the wall representing the symmetry plane. 德国LaVision PIV/PLIF粒子成像测速场仪 Imager SX PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
