Resumo(s)
The present paper reports a numerical study of a spray impinging on a surface through a crossflow and is aimed at studying the fundamental aspects of the spray impingement phenomena in a three-dimensional configuration, which is relevant to practical engines. Different impinging models were used and the results are compared with measurements and predictions of other authors. The results show a general good agreement with the experiments, and reveal that the splash droplets are very important for the spray development. The performance of droplet impinging models depends strongly on the conditions of pre-impingement.
