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，对于物理模型与对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。 Computational fluid dynamics plays a crucial role in the development of aspirated propulsion, but its current application level is still lower than that of aircraft outflow. In order to make computational fluid dynamics more effective in the field of aspirated propulsion, in addition to the universally applicable principles and methods, the analysis and development of physical models and corresponding mathematical models will be an important aspect. This article describes some of the work done by the Aero-Thermal Key Laboratory of Aeroengine.
