In this study, the behaviors of falling droplets on various microchannel surfaces, which were heated to higher temperature (150 ℃~) than boiling point had been investigated. The Leidenfrost temperatures(TLF) on the microchannel surfaces significantly increased compared with that on a flat surface. On the microchannel surfaces with identical channel depth, as the channel width increased from 5 μm to 15 μm, the TLF increased. Also, the increase of the channel depth resulted in the increase of the TLF. The microstructures can give additional hydraulic resistance for evaporating vapor flow beneath liquid-vapor interface on the hot surface, and it causes the increase of the pressure in the thin vapor layer. At the surface temperature range from 150 ℃ to TLF, the droplet contacting to the microchannel surface showed completely different behavior. And, on the microchannel surfaces at relatively higher temperature (200 ℃~), vigorous flattening, which would significantly increase the surface energy of the droplet, and the explosive jumping of the droplet could be observed. Considering potential and surface energies of initial droplet, additional energy source is required to explain the phenomena. In this study, as a candidate for the driving force to the droplet, vapor recoil force has been considered.
