圆锥形送风射流特性的研究
Study on air distribution characteristics in taper jet stream
摘要：
研究了不同圆锥顶角及边壁条件下射流流场。实验表明圆锥形送风分散射流存在一个临界角，若偏离此角，分散射流因失稳而发生向上或向下的偏移，出现贴附射流。

Abstract：
Studies the jet stream field under different point angles and boundary conditions. Experiment results show that taper diffusion jet stream has a critical angle. Diffusion jet stream will lose stability and deviate up or down and adherence jet stream will occur if the point angle is over the critical one.
