Sandwich heating film boiling heat transfer research in narrow rectangle channel
The narrow rectangle channel heat transfer technique is a new developing heat transfer technique in recent years. In the narrow rectangle channel, film boiling is an important two-phase flow heat transfer process in many engineering application, including steam generator, nuclear reactor and engineering metallurgy. As the temperature of droplet, steam and wall are decided by forced convection heat transfer between the steam and the wall, the droplet and the wall, the steam and the droplet and radiation heat transfer process, which makes heat transfer mechanism of film boiling be difficultly interpretative. Film boiling in narrow rectangle channel is analyzed in the paper, investigating the influence of all kinds of heat transfer processes on film boiling. A rectangle channel film boiling model has been built up using thermodynamic non-equilibrium model.
