Abstract
The heat transfer for film quenching was investigated theoretically and experimentally. With the aid of a mathematical model analytical equations were deduced, with which the locally transferred heat‐flux density and the local thickness of the vapour film can be calculated during stable film boiling. The equations were confirmed by experimental results. Accordingly, the heat transfer can be technically influenced only by the velocity of the water leaving the nozzle. With increasing jet velocity of the water not only the transferred heat flux during stable film boiling becomes higher but also the thickness of the vapour film becomes smaller, so that the film collapses earlier, causing the Leidenfrost temperature to shift to higher values.
