Our experiments have shown that the thermally insulating character of the membrane is essential to stop the Leidenfrost effect. The membrane is subject to thermal diffusion from the hot solid and convective cooling from evaporative vapour. Nair et al.8have shown that a hairy surface can significantly delay … Visa mer SiO2 nanofibrous membranes with pore size larger than 1 μm were fabricated via electrospinning of the polyvinyl alcohol (PVA)/silane solution. … Visa mer The experimental set-up mainly consists of an induction heater, a syringe pump, a high-speed camera, an infrared camera and a data collection system. The induction heater is used to maintain the samples at a … Visa mer The mean pore size d in the membrane was measured by capillary flow porometry (porometer from the 3G series of Quantachrome). The experiment consisted of measuring the air … Visa mer The experiments presented in our Article were performed during the Spring of 2024. Then samples were stored in a box without any particular care (ambient atmosphere), and a … Visa mer 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.

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. Webb27 jan. 2024 · The Leidenfrost effect is a physical phenomenon discovered in 1756, which refers to the levitation of drops on a surface that is significantly hotter than the … WebbHere we report a rational design of structured thermal armours that inhibit the Leidenfrost effect up to 1,150 °C, that is, 600 °C more than previously attained, yet … cabarrus county court cost
