The basic problems of transition in both incompressible and compressible boundary layers
are reviewed. Flow structures in low-speed transitional and developed turbulent boundary …

Experiments are performed to investigate the effect of nose-tip bluntness on the instability
mechanisms leading to boundary-layer transition on a, the schlieren visualization region is …

The existing database of transition measurements in hypersonic ground facilities has
established that as the nose-tip bluntness is increased the onset of boundary-layer transition …

Numerical and experimental studies have demonstrated laminar–turbulent transition in
hypersonic boundary layers over sharp cones via the modal growth of planar Mack-mode …

The influence of high levels of wall cooling on the stability of hypervelocity boundary layers
is investigated. Such conditions are relevant to experiments in high-enthalpy impulse …

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 …

Direct numerical simulations (DNS) were carried out to investigate laminar-turbulent
transition for a blunt (right) cone (half-angle) at Mach 5.9 and zero angle of attack …

A thermoacoustic interpretation of Mack's second-mode instability is proposed. It is
demonstrated that the fundamental mechanism of second-mode wave growth in hypersonic …

A new numerical approach for simulating nonlinear wavepackets in hypersonic boundary-
layers is presented. The adaptive mesh refinement wavepacket tracking (AMR-WPT) method …
