000014548 520__ $$2eng$$aThe Leidenfrost effect is studied for drops on a superheated yet non-volatile liquid pool, and contrasted with the more classical situation implying a solid substrate. Experiments reveal the absence of a critical superheat for drops to “levitate” over the roughness-free liquid surface, even when the latter is significantly deformed (i.e. for large drops). Inspired from a previous work, a theoretical model is presented which compares fairly well to experiments without any fitting parameter. Contrary to the case of a solid substrate, the vapor film here does not appear to form chimneys, even for large drops. The evaporation dynamics is also studied, and scaling laws are discussed versus classical ones.
