喷射型诱导风口诱导比的实验研究
Experiment of induction ratio of the diffuser with nozzles
摘要：
以喷嘴的几何尺寸和一次风风量为变量，对喷射型诱导风口的诱导比进行了实验研究。结果表明，喷嘴几何尺寸的变化对诱导比的影响较大，一次风风量变化对诱导比的影响较小。当喷嘴的几何尺寸一定时，随着一次风风量的增加，风口的诱导比缓慢递增。

Abstract：
Taking dimension properties of the nozzle and the primary air rate as variables, performs an experimental research of the induction ratio. The result shows that the impact of the nozzle size is more obvious than that of the primary air rate. When the size of the nozzle is constant, the induction ratio increases slowly with the increasing of the primary air rate.
