Abstract

A large variety of fluid dynamic problems is characterized by strong deformations of the air-water interface. A body moving in water or standing in a current can lead to the breaking of the free surface, air entrainment and generation of vorticity. The study of all these aspects for a generic 3D body can be extremely difficult, particularly because the different phenomena involved interact with each other. With the aim of understanding the physical mechanisms present, both numerical and experimental analyses have been performed for the canonical case of a 2D flat plate moving in initially calm water. This simple problem not only provides a way of studying the fundamental elements described above, but also constitutes a valid benchmark for the validation of the numerical codes dealing with strong deformations of free surfaces and wave-body interactions.
