Abstract
Numerical simulations of the free surface dynamics in an incompressible inviscid
fluid are carried out by integrating the Euler equations in Lagrangian
form. The present work faces a preliminar analysis of the link between pressure
field and free surface motion, with the final aim to investigate the use
of a conformal mapping technique, to simulate the free surface dynamics.
1 Introduction
The free surface dynamics is a relevant issue, specially in the framework of
the naval engineering. It plays a crucial role in evaluating the wave component
of the drag acting on a ship, or the hydrodynamics loads experienced
during the impact of a solid body and the surface. In particular, this second
kind of flow has been deeply investigated in Literature, both from the theoretical
(see, for example, [I]
