dc.description.abstract | Generally, three classified hydrodynamic behaviors of impinging water drops involving corresponding boiling heat transfer regimes have been reported under low Weber number conditions (We < 20): contact boiling (nucleate boiling), transition rebound (transition boiling), and Leidenfrost rebound (film boiling). In previous studies of drop impingement on a structured surface, an explosive lift-off regime, which is characterized by lift-off from the surface within 1 ms without any disturbance at the top side of the drop, was reported, and the triggering hypothesis of explosive lift-off suggested had no quantitative evidence. In this study, the outcomes of water drop impingement onto a heated surface with micropillar arrays were investigated using a high-speed imaging system, for wall temperatures between 150 and 380 degrees C and a Weber number of approximately 4. Pool boiling experiments were conducted to validate the triggering hypothesis of explosive lift-off, as suggested by previous researchers. Based on the experimental results, the triggering mechanism of the explosive lift-off is discussed. | - |
