Abstract

This thesis deals with the study about the emulsion fuel spray characteristics using the optical accessible chamber. The Computational Fluids Dynamics (CFD) is used to illustrate how the spray developed in the chamber and the spray characteristic could be predicted. The overall macroscopic spray characteristic such as the spray penetration length and the spray cone angle were measured manually. The different percentage of emulsion fuel is used; 5%, 10% and 15% of emulsion is tested at the same injection pressure 70MPa which is high pressure and 1MPa of high ambient pressure in the chamber but in different size of nozzle diameter; 0.2 mm and 0.6 mm. The development process and the timing injection in the test were very similar. Moreover, 15% of emulsion which is a higher percentage of emulsion fuel induced shorter penetration length at smaller nozzle diameter and wider cone angle at bigger nozzle diameter. However, there are discrepancies of the result due to improper boundary condition and inherit limitation of the model. For further study process, the emulsion process should be done by the owner-self so the more data from experimental work is needed such as properties of emulsion could be implemented in the study.
