Abstract

This study conducted droplet combustion experiments on diesel, palm oil, and canola oil containing water to compare and analyze droplet combustion characteristics. This experiment was performed depending on the changes in various droplet diameters of 1.387 ~ 1.731 mm of diesel(D100), biodiesel(BDC100 and BDP100), and water emulsion diesel and biodiesel(D-W, BDC-W, and BDP-W) to compare combustion behaviors such as ignition delay, micro-explosion, flame extinction and lifetime. As a result of the experiments, viscosity makes micro-explosions strong, and strong micro-explosions have the effect of reducing flame extinction time and lifetime. The difference between a micro-explosion and ignition delay with diesel emulsion fuel and biodiesel emulsion fuel is considered to be the difference in properties between the two fuels. The emulsion fuels had a great influence on micro-explosion, flame extinction, and lifetime depending on the viscosity of the fuel. However, diesel emulsion fuels with weak micro-explosion showed increasing ignition delay due to the high latent heat of the water. Based on this, it plans to conduct experiments on the effect of the difference in fuel viscosity on combustion behavior.
