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 ...

Rotating boundary layer dynamics is a critical field within fluid mechanics that addresses the behaviour of fluid layers adjacent to rotating surfaces. The interplay of centrifugal forces, Coriolis ...

Understanding the boundary layer transition and the influence of surface roughness in hypersonic flows is critical for advancing aerospace design and safety. At these extreme speeds, the interplay ...

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 ...

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 ...

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence 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 ...
