A three-dimensional direct numerical simulation (DNS) with Level-Set method is applied to the impingement process of a single droplet on the air-water free surface, and the characteristics of the vortices induced below the free surface are investigated by comparing with the experiments. The results show that computed vortex intensities correspond with the best-fit curve proposed by experiments. The comparisons of velocity vectors and scalar concentration fields between the vertical and oblique impingements show that the momentum and scalar transfer mechanisms are quite different between them.
