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

Accurate prediction of boundary layer transition is extremely important for the aerodynamic
and aerothermodynamic design of a hypersonic vehicle. Crossflow instability plays a crucial …

This article reviews the hypersonic laminar-turbulent boundary layer transition over a blunt
circular cone under support of the National Key Research and Development Program of …

High-speed laminar-to-turbulent transition over blunt bodies is relevant to a variety of
aerodynamic applications. Experiments have observed that beyond a critical value of the …

Under the auspices of NATO STO AVT-240:“Hypersonic Boundary-Layer Transition
Prediction”, this paper describes the results of close collaborations among the authors …

The fundamental understanding of the Sanal flow choking and/or sonic fluid throat effect
(VRS Kumar et al., Physics of Fluids, 34 (4 & 10), 2022) in real-world fluid flow system sheds …

ABSTRACT A physical mechanism by which nose bluntness suppresses second-mode
instability is proposed. Considered are 7 degree half-angle straight cones with nose …

An overlap of two heating peaks in a Mach 6 hypersonic boundary layer over a flared cone
with a small nose bluntness at a freestream Reynolds number of 10.0× 10 6 m− 1 is …

We identify and quantify a seemingly overlook mechanism for energy transfer between
adjacent frequency disturbances in the Nonlinear Parabolized Stability Equations method …

Combined-cycle engine is a potential propulsion system for hypersonic aircraft. To ensure
long-term, normal operation of combined-cycle engine under the harsh environment of high …
