The dimples on a golf ball help it cut through pressure drag—the resistance encountered when an object moves through a fluid—allowing it to travel about 30% farther than a smooth ball. Inspired by this aerodynamic advantage, a research team from the University of Michigan’s Department of Mechanical Engineering is exploring the use of dimpled surface technology on submarines. Their goal: to potentially eliminate the need for traditional maneuvering appendages like fins or rudders. Dive into their innovative development process in this Michigan Engineering research spotlight.
