Abstract
An experimental study has been carried out to reveal the statistical characteristics for the onset of micro-explosion of an emulsion droplet evaporating on a hot surface under high pressure conditions. The oil-in-water emulsion consisting of base fuel and water doped with small amount of surfactant is tested after degasification. The base fuels employed are n-hexadecane, n-tetradecane and n-dodecane. The water content of emulsions is varied from 0.1 to 0.2 by volume. Experiments are made at various surface temperatures and ambient pressures. The Weibull analysis is applied to obtain the distribution function of the waiting time for the onset of micro-explosion and to derive the empirical formula for the rate of micro-explosion as a function of water volume and emulsion temperature. The results show that the waiting time is correlated well with the Weibull distribution of the wear-out type. The waiting time decreases with an increase in the ambient pressure, saturation temperature of base fuel, water content and surface temperature. An empirical formula is proposed for the rate of micro-explosion as a function of water volume and emulsion temperature.
