Abstract
We develop a mathematical model of a recently discovered puzzling phenomenon of levitation of droplets near heated solid surfaces at temperatures far below the Leidenfrost point. Coupled heat transfer, vapor diffusion, and Stefan flow around a spherical droplet are accounted for. Predictions of levitation height based on the model agree with the experimental measurements.
