Some Experimental Aspects of Turbulent Diffusion Flames and Buoyant Plumes from Fire Sources Against a Wall and in a Corner of Walls

Abstract Measurements of temperature distribution and visible flame height were made on the fire plumes from square burners in a semi-infinite space, against a wall and in a corner of walls, Flame height is formulated as a function of Q * = Q/poC p T og3/4 D 3/4;52 and the maximum temperature on each height was formulated with the concept of virtual heat source. According to the comparison of the results on the fires against a wall and, n a corner of walls with those in a semi-infinite space, the existence of walls near a fire source is thought to suppress the growth of eddy scale in the plume. The characteristics of natural fuels as sources of turbulent diffusion flame are also discussed.
