Abstract
In a previous paper, a phenomenological-3-D integrated approach to simulate gas injection has been presented and validated. This model has been implemented in a modified version of the KIVA 3V code. In this paper the model is used to perform the analysis of an impinging gas jet. The interaction between impinging jet and airflow plays a fundamental role in mixture formation and thus on the evolution of combustion process and pollutant formation. This is particularly true if considering stratified charge engine with late cycle injection. In this paper three wall jet treatments are considered: two different laws of the wall and a no-slip simulation in order to evaluate their feasibility in capturing the jet evolution. Numerical results are validated by comparison against experimental data found in literature.
