| 摘 要： | 研究收缩型喷嘴在初始压力为100 MPa,出口直径为1 mm的情况下喷嘴流场的速度、压力、湍动能等物理量的分布规律。选择不可压Reynolds方程作为动量方程,利用Fluent的SIMPLEC算法进行求解,对收缩型喷嘴射流进行数值模拟。结果表明:流体速度在喷嘴收缩段迅速增加,在离开喷嘴后出现等速流核区;流体动压在喷嘴收缩段增长快速,在等速流核区保持不变;仿真结果与理论推导相符合。

| Abstract: | This paper numerically studies the distribution regularities of the physical quantity of velocity,pressure,rapid kinetic energy and so on,in the flow-field of the contractive nozzle,when the initial pressure is p=100MPa and the outlet outside diameter is 1 mm.The incompressible Reynolds equation is to selected as the momentum equation and the algorithm of SIMPLEC of Fluent is used to simulate the injection stream.The results show that the jet velocity increases quickly in the contractive section of nozzle a... |
