计算流体力学在吸气式推进领域中的某些应用

计算流体力学对于吸气式推进的发展具有至关重要的作用，但目前的应用水平尚低于飞行器外流领域。为了使计算流体力学在吸气式推进领域发挥更大的实效，除了普遍适用的原则和方法之外，对于物理模型地应数学模型的分析与发展将是一个重要方面。本文介绍了航空发动机气动热力重点实验室所开展的部分工作。

Some Applications of Computational Fluid Dynamics in the Field of Air Breathing Propulsion

The computational fluid dynamics takes an important role in the field of the air breathing propulsions,but its applied standard stall falls short of what the external flow of aircraft at present.In order to bring the compuational fluid dynamics into full play in the field of air breathing propulsions,the research and application of physics and mathematics models will be the important aspect in addition to the general principles and methods.In this paper,some research jobs of Chinese National Aircraft Engine Laboratory are introduced,i.e.,the rotor/stator interaction models in turbomachinery,the swept aerodynamics design of transonic fans/compressors, the numerical simulations of flow field of intake and exhaust components.
