EXPERIMENTAL INVESTIGATION OF COMBUSTION PHENOMENA IN A BINARY DROPLET SYSTEM.

An experimental investigation has been performed to study the interference effects during the combustion of two simulated fuel drops arranged in a horizontal configuration. Methanol and n-hexane were employed as the fuels. Both upwards and downward ambient air flow, and the effects of grid-generated turbulence have been investigated. The quantitative measurements included mass consumption rates and extinction velocities, as a function of flame type, ambient turbulence, air flow direction and sphere spacing. Qualitative information regarding flame geometry was obtained by means of direct, shadow and schlieren photography. In general, interference affects mass consumption rates significantly and extinction velocity marginally, while turbulence has the opposite effects.
