From primary instabilities to secondary instabilities in Görtler vortex flows
Advances in Aerodynamics, 2019 We have studied the transformation process from primary instabilities to secondary instabilities with direct numerical simulations and stability theories (Spatial Biglobal and plane-marching parabolized stability equations) in detail. First Mack mode and

The Aerodynamics of Reacting Substances [PDF]
Proceedings of the National Academy of Sciences, 1939 Speaking broadly, the subject of aerodynamics is concerned not only with the forces exerted by a single fluid on solid bodies but also with the behavior of mixtures such as those which occur in the gasoline engine and in the atmosphere. In a complete study of the motion of a fluid attention must be paid to reactions between its constituents ...

A decomposition formula for the wall heat flux of a compressible boundary layer
Advances in Aerodynamics, 2021 Understanding the generation mechanism of the heat flux is essential for the design of hypersonic vehicles. We proposed a novel formula to decompose the heat flux coefficient into the contributions of different terms by integrating the conservative ...
