Title

Modeling And Experimental Study Of Pure And Blended Bio-Fuel Droplets Injected Into Hot Stream Of Air

Abstract

The combustion dynamics and stability is dependent on the quality of mixing and vaporization of the liquid fuel in the pre-mixer. The vaporization characteristics of different blends of bio fuel droplets injected into the air-stream inside the pre-mixer have been modeled. Two major alternate fuels analyzed are Ethanol and Rapeseed Methyl Esters (RME). Ethanol is being used as a substitute of gasoline, while RME has been considered as an alternative for Diesel. In the current work, the vaporization characteristics have been studied for pure Ethanol and RME in a hot air jet of 800 K in temperature. It was also important to study the behavior of the fuels when they are mixed with conventional fuels, like gasoline and diesel. Results for different percentage-blend of bio-conventional fuel mixture have been compared with respect to temperature gradients and vaporization efficiency. The effect of non-volatile fuel impurities on the vaporization characteristics has also been studied. The model was validated using an experiment which involved heating of levitated fuel droplets to visualize and quantify the vaporization characteristics of different bio-fuel blends.
