Researchers show mechanics of how drag on a partially submerged object may be several times greater than drag on a fully submerged object made of the same material. One of the most common and ...

Grooved channels represent a vital area of research in fluid dynamics where the interplay between geometry and flow control is exploited to reduce drag and enhance energy efficiency. By incorporating ...

Drag torque in wet clutches arises from the viscous shearing of lubricants in the narrow gaps between clutch plates, and it represents a significant source of power loss in automotive and industrial ...

When we first saw the original Tesla Cybertruck, we quickly questioned the aerodynamics of its origami wedge shape. That pointy roof looked like a sure-fire turbulence generator, and turbulent flow is ...

PROVIDENCE, R.I. [Brown University] — One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing ...
