高雷诺数流动的边界层理论在具有大梯度的小区域局部失效，其中需要特殊解，初始压力未知。例子包括在表面几何结构不连续点附近或在分离点附近的流动。在过去的15年中，人们对层流的局部相互作用问题进行了广泛的研究，特别是对分离的描述和预测，并对湍流进行了一些研究。描述了渐近局部相互作用理论的基本思想，并总结了在各种流中的应用。
Boundary-layer theory for flows at high Reynolds number fails locally in small regions with large gradients, where special solutions are required, with the pressure initially unknown. Examples include the flow near a discontinuity in surface geometry or near a separation point. During the past 15 years, local-interaction problems have been studied extensively for laminar flows, with particular attention to the description and prediction of separation, and a few examples have been worked out for turbulent flows. The basic ideas of asymptotic local-interaction theory are described, and applications are summarized for a variety of flows.
