Abstract
Experimental study has been conducted to clarify the heat transfer characteristics of emulsified fuels composed with hydrocarbon and water with a small amount of surfactant and additional component. The focus is mainly paid on the effect of additions of ethanol and fatty acid methyl ester (i.e. FAME) produced from biomass on the heat transfer coefficient and its hysteresis. Heat transfer coefficient was determined using an electrically heated horizontal Pt wire, which is 0.2 mm in diameter and 100 mm in length for various ambient emulsions temperature. It is concluded that heat transfer coefficient increase in the higher emulsion temperature conditions, which occurred by the changes in its viscosity of test emulsions. The effects of alcohol and FAME additives on heat transfer coefficient of water in fuel emulsions were also revealed.
