| 摘 要： | 用Fluent软件对喷嘴的各个结构参数对射流流场的影响进行了数值模拟,模拟发现:在圆锥段收缩角为13°左右、喷嘴出口圆柱段的长径比为3左右时,射流核心段上的速度最大。数值模拟结果与理论结果完全一致。

| Abstract: | The numerical simulation was carried out on the nozzle efflux by using the Fluent software.It has been discovered by simulation that while the contraction angle of the conical segment is around 13° and the length diameter ratio at the cylindrical segment of nozzle exit is about 3,the speed of the core segment of efflux will be maximum.The result of numerical simulation was totally coinciding with the result of theory. |
