“…Staat et al observed two transitions in the experimentally obtained phase diagram for impacting ethanol droplets and identified four boiling regimes including deposition, contact-splash, bounce, and film splash. Jiao et al focused on droplet impact behavior on the superheated laminar particles at various temperatures and defined six typical characteristic patterns, including film evaporation, bubbly boiling, immersion boiling, sputter boiling, transition boiling, and film boiling. The Leidenfrost point of droplets on the laminar superheated particles was found to decrease with the particle size, which was related to the effect of the pore space generated between the laminar particles.…”
