航天飞行器外部绕流与发动机内流均涉及湍流问题,湍流已成为现代飞行器设计中的重要元素之一。对边界层和混合层等模型问题的研究给出了湍流的一些机理认识,这些认识可指导飞行器中的湍流应用。
Turbulence problems are involved in the external flow around the spacecraft and the internal flow of the aircraft. Turbulence has become one of the most important elements in the design of modern aircraft. Studies of model problems such as boundary and mixed layers provide some mechanistic understanding of turbulence that can guide turbulence applications in aircraft.
