Abstract
In the quest for drag reduction, superhydrophobic surfaces have recently attracted a growing interest. These superhydrophobic surfaces are rough surfaces that have the ability to entrap pockets of gas on the surface, essentially allowing the overlying flow to slip over the surface, resulting in a drag reduction. This talk will discuss the common drag reduction mechanism that allows surfaces (e.g. superhydrophobic surfaces, riblets, permeable media) to reduce drag in turbulent flows, and how drag reduction can be explained by a simple model. Then we will focus on isolating the effects that slip and roughness have on the overlying turbulence of superhydrophobic surfaces.
Series This talk is part of the Engineering Fluids Group Seminar series.
