Inhibiting the leidenfrost

WebbThe Leidenfrost effect, namely the levitation of drops on hot solids 1, is known to deteriorate heat transfer at high temperature 2. The Leidenfrost point can be elevated by texturing materials to favour the solid–liquid contact 2–10 and by arranging channels at the surface to decouple the wetting phenomena from the vapour dynamics 3. WebbStructured thermal armours on the surface of a solid inhibit the Leidenfrost effect, even when heated to temperatures in excess of 1,000 °C, pointing the way towards new cooling strategies for high-temperature solids. Zuankai Wang Attention! At Life Science Network we import abstract of articles published in the most popular journals.
