Inverted Drafting Inverted drafting happens when a leading object encounters less drag than the object behind it. An example is when flows encounter passive objects, like flags, arranged one behind the other. Flags are considered passive because they flop around with every shifting breeze, unlike humans who are considered rigid objects. In this image, two white, S-shaped lines are flags oriented one behind the other. The flag in the follower position cuts into the wake given off by the…

In fluid dynamics, we like to classify flows as laminar—smooth and orderly—or turbulent—chaotic and seemingly random—but rarely is any given flow one or the other. Many flows start out laminar and then transition to turbulence. Often this is due to the introduction of a tiny perturbation which grows due to the flow’s instability and ultimately provokes transition. An instability can typically take more than one form in a given flow, based on the characteristic lengths, velocities, etc. of…
