ABSTRACT

The formation of liquid film adhered on the wall during the spray/wall interaction is of great importance due to its close association with the combustion and emission characteristics of engines. In the present study, a new splashed mass ratio sub-model in an improved spray/wall interaction model was developed based on the recent measurements of spray impingement rather than those of single droplet/wall interaction. It was found that the new model could satisfactorily reproduce the film quantity, especially under high-injection-pressure conditions. Then, by coupling the new model with KIVA-3V code, the effects of ambient gas temperature and density, nozzle diameter and injection pressure, impingement distance, and injection mass on the film quantitative characteristics in a constant volume chamber were systematically investigated under diesel premixed charge compression ignition (PCCI) relevant conditions. Finally, dimensionless film ratio correlations, which could qualitatively predict the effects of the related parameters on the film quantity under a wide temperature range (from room to high temperature), were developed based on the experimental and numerical results.
