Optimal nose shaping for delayed boundary-layer separation and transition in axisymmetric flow

轴对称流动中延迟边界层分离和过渡的最佳机头形状。本项目的目的是设计一种光滑的机头，用于放置在高雷诺数粘性流体的轴对称流动中，使机身上的边界层保持不分离。这总是可以用足够长的鼻子来完成，但我们的目标是将必要的鼻子长度降到最低。外部势流将通过环形源提供。势流将被用来确定内边界层解。将通过进行二维和三维稳定性计算来考虑过渡到湍流。

Optimal nose shaping for delayed boundary-layer separation and transition in axisymmetric flow. The aim of this project is to design a smooth nose for a body of revolution placed in axisymmetric flow of a viscous fluid at high Reynolds number, such that the boundary layer on the body remains unseparated. This can always be done with a sufficiently long nose, but our objective here is to minimise the necessary nose length. Outer potential flows will be provided via ring sources. The potential flows will be used to determine inner boundary layer solutions. Transition-to-turbulence will be considered by undertaking 2D and 3D stability computations.
