Abstract
CFD (Computational Fluid Dynamics) simulations are widely used for the research and development in the field of thermal fluidics, including internal combustion engines Spray breakup models significantly affect the liquid film formation on the intake port wall impingement and mixture formation. However, there is no model for the atomization process under port fuel injection conditions with the plate-type multi-hole nozzles which have great atomization characteristics. The purpose of this study is to investigate the spray atomization process and predict the breakup process in multi-hole nozzle spray for port fuel injection. In previous studies, the authors have experimentally investigated the liquid sheet breakup process and droplet behavior of fuel sprays under port fuel injection conditions, and have modeled the droplet generation process based on the liquid sheet breakup theory. In this report, liquid sheet breakup model was modified and simulated the spray atomization process.
