Wetting layer evolution and interfacial heat transfer in water-air spray cooling process of hot metallic surface

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