Summary
The report presents a heat transfer model and correlation of natural-convection film-boiling heat transfer with interfacial wave motion under subcooled conditions. The vapour-film-unit model developed for saturated film boiling in a previous report was extended to subcooled film boiling along inclined and vertical flat-plates and also around horizontal cylinders of large diameter. Based on the vapour-film-unit model, a general form of heat transfer correlation of film boiling with wave motion was developed. Comparison with experimental data showed that the present heat transfer model and correlation can predict the effects of the fluid properties, liquid subcooling, wall superheat, the geometry and the size of the heat transfer surface on film-boiling heat transfer with wave motion.
