| 摘 要： | 本文采用实验和数值模拟的方法，在吹风比分别为0．5、1．0、1．5、2．0的情况下，研究了圆柱单孔二次射流的贴壁性及速度分布。通过对比不同截面位置的流动轨迹和速度分布，发现圆柱孔射流流场的速度分布与圆柱扰流流场的类似。射流出口的最大速度并不位于射流孔中心位置，u值也不是在射流孔中心位置最高。

| Abstract: | This paper use experimental and numerical studies to present the stream path and velocity field of jet flow.Measurements are performed in several blowing ratios(MR=0.5,1.0,1.5,2.0).When comparing the velocity field from different positions,we find that secondary inject flow field shares some similar char-acteristics with cylinder flow.At the outlet of the inject hole,the highest u or velocity magnitude does not e-merge in the center of the hole. |
