Hypersonic flows are energetic and result in regions of high temperature, causing internal
energy excitation, chemical reactions, ionization, and gas-surface interactions. At typical …

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

A novel optical method is used to measure the high-frequency (up to 3 MHz) density
fluctuations that precede transition to turbulence within a laminar boundary layer in a …

The results of a seminal experimental study of the effects of bluntness and swallowing length
on transition on an 8 deg cone at zero angle of attack in Mach 6 high-Reynolds-number flow …

Boundary-layer transition was studied on a sharp 7 deg cone in two hypersonic wind tunnels
at Mach numbers of 5, 6, 8, and 14 over a range of freestream Reynolds numbers between …
