Study of Diesel Spray by Three Dimensional Pseudo High-Speed Photography

摘要

Experimental study of diesel spray photography was executed with three dimensional pseudo high-speed photography. Diesel spray was observed and proved that it developed through three steps. At the initial stage, the leading tip of the spray began to interact with entrained gas. At the middle stage, the atomization was actively promoted by the collision between the decelerating leading tip and the overtaking succeeding part. At the final stage, the leading tips having plural horn-like projections ran in parallel.
