Influence of Flow on Longevity of Superhydrophobic Coatings

Langmuir, 28(25), 9759–9766.

By: M. Samaha*, H. Tafreshi* & M. Gad-el-Hak*

TL;DR: Results show that the longevity of the surface deteriorates by increasing the flow rate, and the flow appears to enhance the dissolution of air into water, which leads to a loss of drag reduction. (via Semantic Scholar)
