Abstract

Classical fluid dynamic codes are inadequate in describing severe distortion or splashing of a liquid impacting on a deformable structure. The recently developed discrete particle methods were expected to overcome the difficulties. In these methods, the liquid is modelled by an assemblage of discrete particles; in every time step different particles interact with one another or with the boundaries. Consequently, description of distortion or splashing of the liquid should not represent a problem. In order to check the computational model an experimental facility was built, in which liquid-solid-impacts under well known geometric conditions can be studied. Two types of impact experiments were performed: one without air gap between the liquid and the impacting sol
