Experiments on skin friction reduction induced by superhydrophobicity and Leidenfrost phenomena in a Taylor-Couette cell

•A modified Taylor-Couette (TC) cell was designed to accurately measure the skin drag.•The combined utilization of superhydrophobicity and Leidenfrost phenomena is studied.•Leidenfrost temperature and minimum heat flux to create film boiling both depend on surface wettability.•Drag reduction on heat...
