Abstract(s)
The present paper reports experimental results of a monosized droplet spray impinging on a surface through a crossflow that can be used to assist the development of computational models. Different impinging models are presented and the experimental results are used to provide a first insight into their adequacy to the description of the physical phenomena. The transition criteria between spray impingement regimes presently available revealed important difficulties to predict the corresponding threshold. Presently available numerical models to predict this type of flows require a careful evaluation of their applicability to the particular case.
