Description
Donghui Chen and co-authors studied in 2026 how flow and heat fields evolve in a wet clutch friction pair whose surface carries a frog-inspired hexagonal texture. Wet clutches work under harsh conditions that damage surfaces and cut reliability. Texturing is a known way to improve such interfaces, and the tree frog's toe pad, which grips when wet, gave the pattern.
The team built a three-dimensional fluid model of the textured steel plate and checked it against pin-on-disc friction tests. Extended to a full disc pair, the texture changed the flow field and raised the local peak flow speed by about eight percent over a plain surface in the report. Groove effects on heat are also traced. Readers get a bio-inspired surface design with the flow physics to explain why it should help.
