Abstract
Recent simulations and experiments suggest that flow over superhydrophobic surfaces may exhibit significantly reduced drag in both laminar [8, 9] and turbulent [7, 10] regimes due to the existence of a thin layer of gas on the surface which allows a slip velocity. The current paper explores this using estimates of drag based on high-resolution PIV in a low-Reynolds number turbulent channel flow.
