The combustion features of water-in-diesel fuel emulsions were studied in a single drop combustionchamber by means of high speed shadowgraphs, suspending emulsion drops to a thermocouple in orderto follow their thermal history. Several emulsions were prepared by varying the internal parameters thataffect their stability, such as water volume fraction, water particle size distribution and the amount ofsurfactant. It was found that the emulsion internal parameter which have influence on emulsion stability(water volume fraction and size distribution, quantity of surfactant) also influence the tendency towardsmicro-explosion.

Abstract
The combustion features of water-in-diesel fuel emulsions were studied in a single drop combustionchamber by means of high speed shadowgraphs, suspending emulsion drops to a thermocouple in orderto follow their thermal history. Several emulsions were prepared by varying the internal parameters thataffect their stability, such as water volume fraction, water particle size distribution and the amount ofsurfactant. It was found that the emulsion internal parameter which have influence on emulsion stability(water volume fraction and size distribution, quantity of surfactant) also influence the tendency towardsmicro-explosion.| File | Dimensione | Formato | |
