本文研究了发动机波动转子内部的非定常流动。为此目的，作者开发了一个数值模型，使用现代和有效的最先进的计算方法和建模。通过与已有的分析结果进行比较，验证了该模型的有效性。这使我们能够模拟内部的流动三端口波转子用作压力分配器。我们与美国宇航局的实验结果的压力分配器的比较表明，该模型是非常适合这种类型的流动。最后分析了分压式波动转子的变工况运行，并确定了其运行极限。
This study concerns the analysis of the unsteady flow inside an engine component named wave rotor. A numerical model has been developed by the authors for this purpose, using modern and efficient state of the art calculation methods and modelling. Then this model is validated by comparison with well established available analytical results. This allows us to simulate the flow inside a three-port wave rotor used as a pressure divider. Our comparisons with NASA experimental results on the pressure divider show that the model is well-suited for such types of flows. The off-design operation of the pressure divider wave rotor is finally analyzed versus the most important parameters and its operation limits are determined.
