The study of hypersonic boundary layer transition and instability encompasses the complex processes by which a thin, near-wall flow region shifts from a smooth, laminar state to a highly chaotic, ...

The Gas Dynamics Lab at Princeton University is currently taking part in transition studies on elliptic cone models. Working with the Applied Physics Group, some of the most recent laser diagnostics ...

Boundary layer transition and turbulence modelling represent central challenges in fluid dynamics, with profound implications for the design and performance of aerospace, automotive, and energy ...

The aim is to make aviation in Europe climate-neutral by 2050. An important part of this is reducing the drag of future aircraft, with the wings playing a major role. The wings not only generate the ...

NASA is mounting an experiment the agency hopes will shed light on boundary layer transition, which caused considerable uncertainty during the space shuttle's return-to-flight mission in August 2005.

A typical challenge for re-entry vehicles during flight is an effective control of hypersonic transition and the laminar/turbulent state of the boundary layer. The state of the boundary layer is of ...

Contours of normalized temperature perturbations of optimal responses inside the boundary layer and the entropy layer, and these optimal responses may shift to another type as a change of specific ...

Chris James receives funding from the University of Queensland, the Australian Research Council, and the U.S. Office of Naval Research.. The BOLT II hypersonic flight experiment will launch tonight ...

There is no clearly defined Mach number that marks the boundary between supersonic and hypersonic flight. But Mach 5 is generally taken by aerospace engineers to be where hypersonic speed begins. The ...
