The study of signals, processes, and systems has motivated the development of different
representations that can be used to analyze and understand them. Classical ways of …

Hypersonic boundary layer transition is a hot yet challenging problem restricting the
development and breakthrough of hypersonic aerodynamics. In recent years, despite great …

The long-span bridge has a flexible structure and low damping. And the truss girder section
is relatively blunt, which is prone to vortex-induced vibration (VIV). Initially, the wind tunnel …

Wall cooling has substantial qualitative and quantitative effects on the development of
instabilities and subsequent transition processes in hypersonic boundary layers (HBLs). A …

This research focuses on measurements of a convective shear-layer instability seen
naturally in quiet hypersonic flow. Experiments were carried out in the Boeing/AFOSR Mach …

The purpose of this research was to design, fabricate, and test a plasma-based active flow-
control system to accelerate and delay crossflow-induced boundary-layer transition on a …

We studied the stability of leeward streamwise vortices over a hypersonic inclined blunt
cone under a flight condition by solving the two-dimensional spatial eigenvalue problem …

The influences of the forward-facing step (FFS) and backward-facing step (BFS) on the 7 half-
angle conical boundary layer instability and transition are investigated at different angles-of …

An experimental study on the traveling crossflow instability over a 60∘ swept flat plate was
conducted. The Mach number is 6, the angle of attack of the model is 5∘. The traveling …

The nose-tip bluntness effects on the hypersonic crossflow instability were experimentally
investigated over a 7∘ half-angle straight cone at 6∘ angle of attack. The experiments were …
