ON THE BURNING MECHANISM OF AN ATOMIZED LIQUID FUEL IN A TURBULENT STREAM
Abstract
An evaluation was made of the vapor concentration of an atomized liquid fuel in the flame zone and the mechanism of its decrease was studied. In a range of initial temperatures of 20 to 320 degrees, flow rates from 12 to 98 m/sec, and at various mixture compositions and droplet dimensions, the following was found: (1) The burning mechanism is diffusionary relative to the fuel droplets. No disturbances of this mechanism which would lead to vapor accumulation in the flame zone were discovered. (2) When fuel vapor forms before the flame zone, its burning can take place by joint diffusion with oxygen to the droplet burning zones, or with the formation of an independent vapor- burning zone. (3) When burning lean mixtures, previous partial vaporization of fuel is permissible only if it leads to the formation of an independent burning zone.
