This work is aimed at studying the fundamental aspects of the spray impingement phenomena in a three-dimensional configuration, which is relevant to practical engines. A computational study of the flow produced by a spray stream injected through a crossflow is reported and discussed in detail. Different impinging models were used and the results are compared with measurements and predictions of other authors. A new droplet impingement model was developed and tested. The results show a general good agreement with the experiments, and reveal that the splash droplets are very important for the spray development.engSpraysDroplets ImpingementSecondary Atomizationjournal article
