Characterization of superhydrophobic surfaces for drag reduction in turbulent flow

After several years of study, our work on reducing drag in turbulent flow using superhydrophobic surfaces is published in the Journal of Fluid Mechanics! In this work we show how wettability and roughness contribute to turbulent drag reduction, and we design durable superhydrophobic surfaces that can reduce drag by more than 50% in highly turbulent flow conditions. This could significantly reduce the fuel usage or naval vessels. Check out the article!
