Inhibiting the leidenfrost
WebbInhibiting the Leidenfrost effect above 1,000 °C for sustained thermal cooling. The 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 ...

Webb17 dec. 2010 · Gas- or precipitate-forming reactions can also be performed inside this miniature reactor. Most importantly, reaction products in liquid, solid or gaseous states can be collected effectively, which allows the harvesting of valuable products formed in limited amounts. Such a miniature reactor built on superhydrophobic pedestals provides a new ...

The Leidenfrost effect can have dire consequences in applications that require strong water cooling, such as in nuclear power plants where inefficient cooling due to the Leidenfrost phenomenon can lead to core meltdowns.Evaporating water into steam requires a lot of potential, which is … Webb11 juli 2003 · We observe a narrow enhancement near 2m(p) in the invariant mass spectrum of pp pairs from radiative J/psi-->gammapp decays. No similar structure is seen in J/psi-->pi(0)pp decays. The results are based on an analysis of a 58 x 10(6) event sample of J/psi decays accumulated with the BESII dete …
