摘要

本研究的目的是模拟塞式喷嘴内的流动。进一步研究了流动参数的演化规律。通过仿真计算了喷嘴的质量和排气的质量。并将所得结果与数值计算结果进行了比较。在第二部分的研究中，采用近似方法生成了不同热容比γ值和出口马赫数下的塞式喷管廓形。最后，将我们的结果与数值和实验结果(可在公开文献中获得)进行比较。

Design and Numerical Analysis of a Plug Nozzle

The purpose of this study is to simulate the flow in the plug nozzle. Further, the evolution of the parameters of this flow was studied. The mass of the nozzle and of the exhaust gases was calculated by the simulation. In addition, all these results are then compared with those obtained by the numerical calculations. In the second part of the study, the method of an approximate method was used to generate the profile of the plug nozzle for different values of heat capacity ratio γ and the number of exit Mach. Finally, our results are com-pared with those obtained numerically and experimentally (available in open literature).
