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 ...

In fluid dynamics, the drag coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag ...

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 ...

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 ...
