Investigation on the Characteristics of Diesel Spray : Shape of Multiple Diesel Sprays and Air Movement between Neighbouring Sprays

概要

論文の詳細を見る
This paper presents some experimental results on the shape of multiple diesel sprays and the air movement between neighbouring sprays when injected in the quiescent charge with a high pressure at a room temperature. The following conclusions can be drawn from the experiments : (1)The spray tip penetration, the spray cone angle and the equivalent spray angle are not influenced by the sprays located beside the measured spray. (2)The length of initial part and that of penetration part of multiple sprays are greater than those of single spray. (3)Between neighbouring sprays, there is an air movement in the direction of nozzle tip. (4)The air velocity around spray injected between walls is twice as fast as in the case of no wall. (5)The flame growth in the direction of nozzle tip increases as the number of nozzle holes increases.
