摘要

本文提出了一种在高温条件下设计轴对称塞型超音速喷管的方法。该方法基于高温下普朗特-梅耶膨胀理论，采用特征方法。为此，用FORTRAN语言编写了相应的代码，实现了喷管的设计。一旦后者得到了，我们就对流动的热力学参数如压力、温度和马赫数的演变感兴趣。所得结果与理想气体模型的结果一致。对于设计参数(长度、截面比、推力系数和质量系数)，我们发现PG模型在𝑀𝑀和𝑇𝑇0分别小于2.00和1000𝐾𝐾时给出了非常满意的结果。随着𝑀𝑀和𝑇𝑇0的增加，这会影响性能，需要使用我们的HT模型来纠正计算。为了使该喷嘴的重量最小化，本研究对塞式喷嘴进行了截断研究，以提高其性能。所有的计算都是在空气中进行的。

Design and performance evaluation of a high temperature axisymmetric plug nozzle

In this study, a method for designing supersonic nozzles with axisymmetric plugs at high temperature has been proposed. The approach is based on the theory of Prandtl-Mayer expansion at high temperatures using the method of characteristics. For this purpose, a code in FORTRAN language was developed in order to obtain the nozzle design. Once the latter was obtained, we were interested in the evolution of the thermodynamic parameters of the flow such as pressure, temperature, and Mach number. The results achieved were confronted with those obtained for a perfect gas model. Regarding the design parameters (length, section ratio, thrust coefficient and mass coefficient), we found that the PG model gives very satisfactory results for values of 𝑀𝑀 and 𝑇𝑇0 below 2.00 and 1000 𝐾𝐾, respectively. As 𝑀𝑀𝐸𝐸 and 𝑇𝑇0 increase, this affects performance, requiring the use of our HT model to correct the calculations. In order to minimize the weight of this nozzle, this research is investigating the truncation of the Plug nozzle to increase its performances. All calculations were performed for air.
