Research on field effection analyzing method of diesel spray and mixing process

Matching of diesel combustion system is the core of diesel engine research. A new analyzing tool named field effection analyzing method is proposed in this paper to simulate the Spray, the mixture formation and the combustion process in the chamber of diesel engine in both micro and macro aspect. Two main factors of this method are fuel concentration and velocity of flow field. The action of two factors on mass transfer is quantified by the Field Effection Angle, and to evaluate the combustion system. The matching of spray angle as an example to conduct the simulation by using field effection analyzing method. Verification was made in a single cylinder engine, and the study shows that the field effection analyzing method is an effective and applicable method.
