本文给出热线风速仪测量获得的试验结果,确定了雷诺数 Re、特征比 AR 以及射流初始湍流强度(u′/U)_0对小特征比矩形湍流射流的某些影响。
In this paper, the experimental results of the hot-wire anemometer were obtained. Some effects of the Reynolds number Re, the characteristic ratio AR and the initial turbulence intensity (u ’/ U) _0 on the rectangular turbulent jet with small feature were determined.
