Abstract
The theory of submerged jets is applied quantitatively and qualitatively to diesel fuel sprays, based on simple considerations of the inherent invalidity of the single-particle “ballistic” approach. Approximate theoretical results are obtained for penetration velocity, penetration versus time, and fuel-air ratio within the spray. Modeling experiments are discussed and the jet approach used to explain two types of diesel combustion situations-fuel entrapment by insufficient penetration in the presence of air swirl and the efficacy of the MAN process.
