Small-scale velocity fluctuations in turbulent boundary layers are often coupled with the largerscale motions. Studying the nature and extent of this scale interaction allows for a statistically ...

Using HLRS’s Hawk supercomputer, University of Stuttgart scientists have for the first time produced high-resolution simulation data characterizing the transition from low to high Reynolds numbers in ...

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 ...

The control of small structures and fast modes needs not only more accurate values in the commonly used dimensions (, u, T, P), but also, in fact more essentially, the controls from more dimensions.

In order to push flight technology beyond the supersonic regime, fundamental research on viscous hypersonic flow will be essential. It is widely recognized that this research must have both a strong ...

Reynolds number effects noted from selected test programs conducted in the Langley 0.3-Meter Transonic Cryogenic Tunnel (0.3-m TCT) are discussed. The tests, which cover a unit Reynolds number range ...
