摘要：

This study investigated an effect of nanotubes on a heated surface onto Leidenfrost droplet through high speed visualization and momentum balance analysis. Delayed cutback phenomena and Leidenfrost Point (LFP) by dramatically high heating level were observed, and it is elucidated through wettable and spreadable features induced by nanotubes. As much delayed LFP, transient boiling regime with explosion-like dynamics of a water droplet on the nanotubes was observed. Furthermore, nanotubes required higher wall temperature to maintain non wetting cushion, due to the induced slip condition by porous features. (C) 2013 AIP Publishing LLC.
