Plastron morphology and drag of a superhydrophobic surface in turbulent regime

We perform drag force and particle tracking velocimetry measurements on a body-of-revolution coated with a superhydrophobic layer for $R\phantom{\rule{0}{0ex}}e$ between $5\ifmmode\times\else\texttimes\fi{}{10}^{5}$ and $1.5\ifmmode\times\else\texttimes\fi{}{10}^{6}$. As $R\phantom{\rule{0}{0ex}}e$ increases, drag reduction decreases, and a full plastron becomes isolated air bubbles as thin menisci.
