Abstract
The purpose of this research is to construct a model that can predict the breakup process of direct injection gasoline spray with high accuracy. In this report, the spray breakup model was selected from the experimental analysis results of the spray breakup form just below the injection hole. The reproducibility of spray formation was verified by combining Huh and Gosman model, which is a primary breakup model that considers turbulence in the nozzle, and MTAB model assuming low-speed secondary breakup.
