本文采用k-ε湍流模型，对高速非定常射流的不可压流动进行了计算流体力学分析。拟喷管的概念适用于具有大压力梯度的进口条件。结果表明，甲烷和氢燃料的射流发展时间历程与实验数据一致。此外，该模型还很好地描述了喷射条件对射流尖端发展的影响。此外，还研究了进口条件对湍流度和尺度的影响。© 2006 Wiley Periodicals，Inc. Heat Trans Asian Res，36（1）：1- 12，2007;在线发表于Wiley InterScience（www.interscience.wiley.com）。DOI 10.1002/htj.20141
The flow of a high-speed unsteady jet is analyzed using computational fluid dynamics for an incompressible flow with the k–e turbulence model. The pseudo-nozzle concept is applied to the inlet condition with a large pressure gradient. The results show that the time history of the jet development agrees with the experimental data for methane and hydrogen fuels. In addition, the effect of the injection condition on the development of the jet tip is well described with this model. Furthermore, the effects of inlet conditions of the turbulence intensity and scale on the flow are investigated. © 2006 Wiley Periodicals, Inc.
