What determines the size of giant dunes?

Physicists at the Laboratory of Physics and Mechanics of Heterogeneous Media (CNRS / Université Paris Diderot / ESPCI ParisTech / Université Pierre et Marie Curie) have shown, in collaboration with scientists ...

Putting some skin in the turbulence game

An algorithm that improves simulations of turbulent flows by enabling the accurate calculation of a parameter called skin friction has been developed by KAUST researchers in collaboration with researchers at the California ...

Flow phenomena on solid surfaces

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between ...

Image: Breaking boundaries in new engine designs

In an effort to improve fuel efficiency, NASA and the aircraft industry are rethinking aircraft design. Inside the 8' x 6' wind tunnel at NASA Glenn, engineers recently tested a fan and inlet design, commonly called a propulsor, ...
