New Modelling Approach For Fast Online Calculations In Sprays 2000-01-0287

The goal of this paper is to obtain a simple fast model that provides information about the spray tip penetration (for free and wall jet), droplets velocity distribution and fuel concentration distribution. This model would be an important first step in the construction of a simple model capable to provide online information about the spray behaviour in engine conditions, although for the moment, the model only concerns cold sprays. As this model is based in momentum and mass flux conservation, and the patterns observed in gaseous turbulent jets, its agreement with experimental Diesel results will help to improve understanding of the spray structure in terms of the similarities and differences with a gas jet, as well as of the importance of the spray front structure in its penetration.
