Analysis of Electrospray Characteristics from Emulsion Fuel in Oleic Methyl Ester Blend with Varying Electrode Distances

 

Abstract:

This research reports the experimental investigation of electrospray characteristics from Oleic Methyl Ester/Water emulsion fuel in varying electrode distances. The Oleic Methyl Ester which is the major component in biofuel. Biofuel, such as Biodiesel fuel (BDF) is expected as carbon neutral fuel and contained the water remained in the production phase. From this point of view, making the biodiesel as emulsified fuel is efficiently using the water fractions to control the overall temperature in combustion, which is called as the low temperature combustion (LTC). In addition, the emulsified fuel has the large electric conductivity, thus, it is possible to control the size of atomized particle and cause the secondary atomization occurred, which results in micro-explosion to advance the thermal efficiency, by charging the electrostatic energy. In this paper, the Oleic Methyl Ester/Water emulsion is tested with the electrostatic energy and discussing in several different electrode distances to figure out the electrospray characteristic by using high-speed camera under the maximum 120000fps and evaluate the non-uniformities of electric field. As the result, the electro distances affect the electrostatic atomization of Oleic Methyl Ester/Water emulsion and provide the further detail information for academic research. The particle size distribution and droplets’ diameters were measured and discussed from video to understand the electrostatic atomization characteristics.
