Welcome back to The Environmental Review Podcast. In today’s episode, we’re diving into a fascinating intersection of fluid dynamics, biomimicry, and robotic design. New research from the University of Michigan introduces a golf-ball-inspired prototype with dynamically adjustable dimples that can drastically reduce drag and even steer itself—no fins, no rudders, just smart surface control. To unpack the science behind this innovation, we’re joined by Dr. Anchal Sareen, assistant professor of naval architecture and mechanical engineering at the University of Michigan, and lead author of two new studies published in Flow and Physics of Fluids.
