Investigation of Combustion Mechanism of Combined Combustion of Premixed Gas and Droplets

Abstract

Combined combustion of premixed gas and droplets occurs in the spray combustion. The combustion of this case is the very complicated phenomenon and has not well-clarified. Therefore, in order to investigate the mechanism of combined combustion of premixed gas and droplets, experiment was carried out using a constant volume chamber with an ultra sonic vibrator with a bolted langevin transducer, and an instrument for the formation of premixed mixture for imitating the combined field of premixed gas and droplets. As a result of this experiment, the influence of the change in equivalence ratio of premixed gas, the proportion of liquid fuels and the variety of fuels on combustion were clarified.
