Compared to the streamwise instability, the cross-flow instability in high-enthalpy flows has
received relatively less attention, but the latter is of vital importance in the flow transition for …

A new type-II secondary instability mode was recently identified in high-speed cross-flows
using stability analysis, but its role in the transition process is not yet clear. Here, the …

Experiments have been conducted on a swept wing model in a low-turbulence wind tunnel
at chord Reynolds number of to investigate the unsteady interaction of a forward-facing step …

The boundary layer transition process for a straight circular cone with angle of attack (AoA)
of 6° at Mach 6 was studied via high-resolution direct numerical simulations and stability …

Natural convection in a cavity with a partially heated obstacle at the center at the Rayleigh
number R a= 1.46× 10 9 is investigated using large eddy simulation (LES). The standard …

The linear instability of compressible boundary layers over a flat plate in the presence of
parameterized crossflow has been investigated by means of linear stability theory. A family …

In this work, we numerically investigate the effectiveness of sinusoidal roughness elements
(SREs), which have been proposed by our group to delay crossflow boundary layer …

Linear stability analyses are performed to study the dynamics of linear convective instability
mechanisms in a laminar shock-wave/boundary-layer interaction at Mach 1.7. In order to …

A new experimental facility named Swept Transition Experimental Platform (STEP) has been
designed and built for detailed studies of crossflow instability and its interaction with surface …
