WETTING LAYER EVOLUTION AND INTERFACIAL HEAT TRANSFER IN WATER-AIR SPRAY COOLING PROCESS OF HOT METALLIC SURFACE

ABSTRACT
In order to respond to the increased demand for clean energy without harming the atmosphere through polluting emissions, energy production from the hydrogen combustion become largely used. This work presents a numerical study of the injection conditions effect on the structure of the H2-air diffusion flame. The aim is to reproduce a practical case of non-polluting combustion and resulting in very high temperatures. The configuration is composed of two axisymmetric coaxial jets, as can be found in the diffusion burners. A presumed probability density function approach is used to describe the chemistry-turbulence interaction. The k-ε model of turbulence is used. Particular attention is given to phenomena anchoring or blowout of the flame.
