Researchers find the key to reducing drag on superhydrophobic surfaces can come down to a single parameter
Sometimes, the most complex problems can be solved with the simplest approaches. Such was the case for researchers at UC Santa Barbara as they tried to resolve a longstanding issue of fluid friction—the resistance between an object moving through fluid, or conversely, a stationary object with fluid flowing around or through it. It’s also known as drag.
