Experimental study of radiation heat transfer coefficient of diffusion flames

Tóm tắt

Basing on analysis of flame pictures given by visioscope by two-color method, the paper presents evolution of radiation heat transfer coefficient "s of soot in diffusion flames in air, in furnace and in combustion chamber of Diesel engine. "s reaches respectively its maximal value of 0.15; 0.30 and 0.45 in regions of maximal soot fraction of the three above flames.
