High injection pressure impinging spray experiments and modeling were performed under simulated diesel engine conditions (pressure and density) at ambient temperature. A spray impinged normal to a small crown in the bowl of a simulated piston. High speed photography was used in the constant volume bomb to examine the effect of impingement on fuel mixing. The spray model which includes drop breakup, coalescence, impingement, and vaporization effects was used to predict fuel mixing in the bomb. The spray distributions predicted by the model are compared to the photographs obtained in the bomb.
