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 ...

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 ...
