摘　　要：建立了喷管潜入段二维两相冷流实验设备，进行了相应的实验。实验清晰地显示了在潜入喷管进口背壁凹区旋涡的产生、稳定、消失，以及粒子的冲刷、粘贴、脱落、沉积等反复作用的复杂现象，它们与流动的雷诺数、粒子的含量和尺寸、潜入喷管进口处的形状和潜入深度、背壁型面等因素有关。The two dimensional and two phase cold flow test equipment was built and some experiments were performed.The tests clearly show the repeatedly effected complex phenomena of occuring, staying,falling away and disappearing of the vortex in the back wall concave regions and of eroding,sticking,dropping off and depositing of the particles.They are related to Reynolds number,content and diameter of particle,submerged depth,entrance shape and back wall contour,and so on.
