| 摘 要： | 用二维恒温风速仪及Ｘ探针旋转法对风力灭火机出口三维撞击射流流场进行了实验，完成了渐缩圆形喷口射流以不同角度撞击到板上的三维流场的速度、湍流度及雷诺应力测试，经过适当的数据处理和结果分析，得出风力灭火机宜取２０℃以下喷射角为佳。

| Abstract: | An experimental investigation of the impingement jet from the nozzle of a wind-force extinguisher is presented here. By the X-Probe rotation method, the two channel HWA made by TSI incorporated can be used to measure 3-D flowfields.In the experiment, the jet issued from the circular convergence nozzle and then impinged onto a plate in different angles. The measurement results included 3-D mean velocity, turbulence level and Reynolds stress of the flow-field.After suitable data processing and result analysis,the better spray angle of extinguishing fire by windforce is obtained.It provides beneficial instructions to engineeringuse. |
