The prediction of the laminar-turbulent transition of boundary layers is critically important to
the development of hypersonic vehicles because the transition has a first-order impact on …

Abstract Space–time scale-resolved diagnostic and computational campaigns routinely
produce high-fidelity multi-disciplinary truth-model quality datasets for complex …

Direct numerical simulations (DNS) were performed to investigate the laminar–turbulent
transition in a boundary layer on a sharp cone with an isothermal wall at Mach 6 and at zero …

This paper is the first part of a two-part study on the mechanisms of the receptivity to
disturbances of a Mach 4.5 flow over a flat plate by using both direct numerical simulations …

In this paper, we continue to study the mechanisms of the receptivity of the supersonic
boundary layer to free-stream disturbances by using both direct numerical simulation and …

Supersonic boundary-layer receptivity to different types of free-stream disturbance is studied
for a Mach 4.5 boundary-layer flow over a flat plate by using the approaches of both direct …

Direct numerical simulations were performed to investigate wavepackets in a sharp cone
boundary layer at Mach 6. In order to understand the natural transition process in hypersonic …

The receptivity phenomenon, which is the process of environmental disturbances initially
entering the boundary layers and generating disturbance waves, is one of the important but …

Two-dimensional direct numerical simulation (DNS) of receptivity to acoustic disturbances
radiating onto a flat plate with a sharp leading edge in the Mach 6 free stream is carried out …

和一般的飞行器一样, 在近空间飞行器的研制中, 其边界层的转捩和湍流也是需要考虑的两个
重要问题. 但即使是对一般的飞行器,“转捩” 和“湍流” 也还是两个历经百年而仍未很好解决的问题 …
