Buoyancy Effects on Liquid-Nitrogen Film Boiling in Vertical Flow

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 16)


Film boiling occurs when a continuous vapor film exists between the heat-transfer surface and the liquid. The evaporation of liquid is essentially on the liquid-vapor interface with heat transfer across the film primarily by conduction. This mode of heat transfer has been analyzed for both the pool (nonflow) and forced-flow system. In these analyses, both buoyancy and viscous forces are known to influence the thickness and stability of the vapor film which are recognized as controlling parameters in this heat-transport mechanism.
