Film boiling is a complex phenomenon where the continuous vapour layer prevents wetting of the hotter surface with the colder liquid and consequently inhibits the heat transfer. Recent fundamental research of liquid-vapour interface morphology and boundary layer conditions helped in improvement of the accuracy of heat transfer model prediction for the film boiling driven by natural-convection conditions. Despite significant research efforts, the accuracy of the physically based heat transfer correlations for the forced-convection film boing conditions are still low.
Our research is motivated by interest in understanding of physical mechanisms that govern the heat transfer in the forced convection film boiling regime. Understanding the basic physics of film boiling in forced-convection conditions may have implications in various realistic applications as for example in the nuclear industry, natural gas industry, steel industry and volcanology.
