Leidenfrost phenomenon on conical surfaces

- Summary

Abstract

Experiments on leidenfrost dynamics of water deposited in conical bowls reveal a maximum evaporation time for a given angle of confinement. The drop profile is numerically computed and the different observed regimes are explained as a result of two mechanisms of vapor release: chimneys, suppressed when confinement increases, and lateral flow along the walls.
