Stereoscopic flow visualization is being used to investigate the structure and evolution of a low Reynolds number turbulent boundary layer. The boundary layer has a Reynolds number based on momentum ...

Recent advances have significantly enhanced our understanding of the complex fluid dynamics surrounding wind turbine blades. By employing non-invasive imaging techniques such as infrared thermography, ...

The flow is from bottom to top. The Reynolds number based on momentum thickness at the midpoint of the volume is 700. A passive scalar has been introduced into the flow along a spanwise line at the ...

In an experiment on how turbulent boundary layers respond to acceleration in the flow around them, aerospace engineers at the observed an unexpected internal boundary layer. In an experiment on how ...

Turbulence makes many people uneasy or downright queasy. And it's given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that arises when ...

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* ...

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 ...

Experiments were conducted in the Unsteady Pressure Gradients Facility in the Aerodynamics Research Laboratory at UIUC. The facility comprises a boundary layer wind tunnel and a removable installation ...
