A non-evaporating transient high pressure diesel spray operating under different ambient conditions was studied.Tip penetration and Sauter Mean Diameter (SMD) were measured using simultaneously the high speed photography and the laser light extinction techniques.Comparisons between experiments and computations were performed. The spray simulations were carried out by KIVA code version two with and without breakup submodel. The effect of the grid spacing on the numerical results was also evaluated.The KIVA simulations consistently underestimate the jet penetration. The computations of SMD are in disagreement with the experiments. These inaccuracies are probably caused by the inadeguate atomization model and, in part, by the limitation of the experimental techniques.
