Summary:

A swirl-type injector is commonly used for the gasoline direct injection IC engines. To control and optimize the engine combustion, analyses of mixture formation process inside the cylinder are quite important. In this study, an evaluation of a DDM (Discrete Droplet Model) including breakup and evaporation sub-models has been made by making comparisons between the calculation and measurement. In the calculation, two kinds of initial conditions were tested; one was from empirical expressions and the other was from calculated results using a VOF (Volume Of Fluid) model that had a feature to examine the free fluid surface of a liquid fuel spray. As a result, the authors have found that a DDM can basically explain the spray formation process. However, much further modification of the breakup model and initial conditions would be required to have a quantitatively good agreement between the calculation and measurement
