Heat Transfer Coefficient Measurements of Liquid Nitrogen Drops Undergoing Film Boiling
Due to the increasingly extreme temperatures required by modern technology, the phenomenon of film boiling of liquids must be dealt with quite frequently. The cooldown of cryogenic tanks and transfer lines and the liquid-injection cooling of a rocket nozzle are two examples where the film-boiling phenomena must be understood if accurate heat transfer predictions are to be made. Film boiling of discrete masses of liquid is commonly referred to as the Leidenfrost phenomenon; this is in contrast to pool film boiling, where the fluid is of essentially infinite extent.
