Based on the results from the structural dynamic analysis using LS-DYNA, to simulate bow and stern collisions for various collision angle and locations, the following conclusions were made; The SPS 20-30-Existing CDH provides an impact...

... dramatically the droplet trajectory, but keeping the velocity normal to the wall equal to zero. Once the droplet reaches the wall by either a strong acceleration field or chance, it interacts with the liquid surface, i.e. it collides. The outcomes of the collision can be of several different types, Yarin (2006...
