We consider the laminar boundary-layer flow past a semi-infinite plate with a stream-wise ridge. We seek similarity solutions to the problem, when the freestream velocity takes the form x* n, where x* ...

We have found that low levels of helium injection near the leading edge stabilizes the turbulent boundary layer, apparently causing a reverse transition to laminar flow to take place. These results ...

If the boundary-layer equations for a gas are transformed by Mises's transformation, as was done by Kármán & Tsien for the flow along a flat plate of a gas with unit Prandtl number σ , the computation ...

Naturally, the risks and advantages of these weapons, many of which are basically here, are inspiring the military services to massively fast-track hypersonics development. For instance, the Army ...

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, ...

Air Force and Army scientists are making progress in their effort to bring hypersonic weapons development to a new level of effectiveness by exploring ways to better manage “heat flow” during ...

The Farnborough debut of Boeing’s latest 787 derivative has enabled details of the aircraft’s aerodynamic advances to be examined close up. The 787-9 is the first Boeing airliner to be equipped with ...

This section was adapted from The Engine and the Atmosphere: An Introduction to Engineering by Z. Warhaft, Cambridge University Press, 1997. How many times a day do we turn on a faucet? Do it now.

In the quest for greater efficiency of large transport aircraft, efforts to reduce wing drag through conventional aerodynamic tweaks have largely been exhausted, in the view of Airbus senior ...
