An analytical study of a mechanism believed to initiate disruptive burning of alternative fuels is reported. Homgeneous nucleation theory is used to predict the threshold thermodynamic state for the vapor explosions of droplets of binary fuel blends which are emulsions and mixtures of miscible liquids. A simple development for the steady state droplet burning temperature is also described. Disruptive combustion is assumed to be initiated when the burning temperature exceeds the nucleation temperature characteristic of the fuel blend. Results are used to predict the initiation of disruptive burning of water in n-alkane emulsions and binary n-alkane mixtures. 29 refs.
