Improved understanding of the combustion properties of emulsified water-fuel mixtures could lead to better energy utilization/emission characteristics for energy conversion systems which employ spray combustion. The combustion properties of emulsified fuels required for guiding optimization of practical applications were studied. The program's goal was to define the combustion characteristics of water-in-fuel emulsions and to experimentally investigate the relationships of emulsion characteristics at the micro-explosion phenomena. Interest in improving operating characteristics of light vehicle diesel power plants to levels acceptable for large scale integration into the private transportation sector originally motivated this program. Aspects of the program are also relevant to use in other combustion systems. Research encompassed emulsion formation techniques, physical characteristics, emulsion coalescence kinetics (stability), single suspended and free droplet combustion, spray characterization and nucleate vaporization (of the internal phase) prediction. Results have been used to critically evaluate published practical results, predict favorable applications for emulsion combustion, and guide full scale implementation research and development elsewhere. This final report summarizes the results and accomplishments of the program.
