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 ...

Air–sea interaction and turbulent boundary layers lie at the heart of exchanges between the atmosphere and the ocean. This field examines the momentum, heat, and scalar transfers across the air–sea ...

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 ...

Shock wave and turbulent boundary layer interactions are phenomena encountered in high-speed flows, where abrupt pressure changes associated with shock waves impinge upon the viscous layer of fluid ...

Abstract: I shall discuss two programs of research that have occupied much of my time and the time of two PhD students with whom I am working: Samantha Sheppard and Jarred Kenworthy. Jarred and ...

Researchers from the Department of Mechanics and Engineering Science at Peking University (PKU), led by Prof. Chen Shiyi and Prof. Yang Yantao, have recently proposed a mechanism to enhance the ...

The boundary layer, a tiny layer on the surface of a body in a flowing fluid, such as an airplane wing in the air, is of paramount importance for the future of flight. Just over 100 years ago, Ludwig ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

The planetary boundary layer (PBL) is also known as the atmospheric boundary layer (ABL). It is the lowest part of the atmosphere and its behavior is directly influenced by its contact with the ground ...
