Analysis of Current Spray Penetration Models and Proposal of a Phenomenological Cone Penetration Model 960773

A phenomenological zero-dimensional spray penetration model was developed for diesel-type conditions for a constant volume chamber. The spray was modeled as a protruding cone which is well-mixed at its tip after passing through initial primary and secondary breakup zones. The resulting cone model is strictly dependent on injection parameters; density ratio, injection and chamber pressure, nozzle characteristics, and cone angle. The proposed model was compared with data from three different sources and performed well in most cases except for low density environments.
