Various methods were examined for determination of the burning velocities of liquid fuel sprays. Difficulties existed in finding the reference flame surface which governed the burning velocity of sprays since spray flames were usually thick and rather unsteady. The surface where the OH radical emission had a peak intensity was more suitable as a reference flame surface than the surfaces determined by schlieren or direct photography. The burning velocities of premixed sprays of kerosene were determined using a carefully-designed premixed spray burner. The coburning characteristic of premixed sprays of kerosene were also determined for the case of propane-kerosene spray-air mixture combustion.
