Abstract
A new spray/wall impingement model for gasoline engines has been developed. The model is based on experimental analysis of impinging spray droplets using a phase doppler particle analizer (PDPA). Three new equations were obtained in terms of droplet size, Weber number and the angle from a wall for droplets which were splashed after impinging or created by the impact of a droplet on the liquid film layer on the wall. The three-dimensional calculation results using the model agree very well with the experimental data. The model is also applied to the fuel mixture formation process in a lean-burn gasoline engine.
