| 摘 要： | 对多股射流与圆柱管中的横流湍流混合的三维流场进行了数值模拟。结果显示，在有约束的横流中射流的发展可发成三个区。三维流场与二维流场有很大的区别，射流下游没有预测到回流区。射流与主流的动量流率比对射流的喷入深度有很大的影响。

| Abstract: | The numerical simulation for the three dimensional turbulent flow field of multiply jets mixing with a confined crossflow in cylindrical duct is presented in this paper. The results show that the jet in a confined crossflow has three main regions. No recirculation near the downstream region of the nozzle opening has been predicted, which is different greatly with the results in two dimensional rectangular duct. Jet to mainstream momentum flux ratio has great influence on the depth of penetration. |
