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 ...

For turbulent boundary layers in supersonic and hypersonic flow, there exist only three experiments which give turbulence data at a Mach number greater than 4 (Fernholz and Finley 1977, 1981): the hot ...

The Boundary Layer Wind Tunnel in the Hele-Shaw Laboratory within the ... allowing steady flow velocities between 0.5 m/s and 35 m/s, with exceptionally low turbulence intensity. The test section, ...

The boundary layer of the canopy is determined by the ... The rougher the canopy, the greater the wind turbulence it creates, and the more wind (and therefore CO 2 and water vapor) moves between ...

Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer ... and the turbulent movement of aerosols throughout ...

"If the boundary layer on a hypersonic vehicle is exposed to atmospheric turbulence along its flight path, aerodynamic drag and heat on the vehicle will increase significantly, affecting control ...
