In this work a variational approach to sloshing problems is presented. Such an appoach is based on the definition of a functional of the fluid motion which becomes stationary in correspondence with the motions of the fluid system. In the present case the fluid is assumed to be inviscid and attention is focused on the Hargneaves-Luke formulation, which consists of defining the functional as the work done by the pressure inside the fluid domain. Such a formulation allows the determination of all the most interesting field variables, namely the velocity, the pressure and the instantaneous and local shape of the moving surface.

Abstract
In this work a variational approach to sloshing problems is presented. Such an appoach is based on the definition of a functional of the fluid motion which becomes stationary in correspondence with the motions of the fluid system. In the present case the fluid is assumed to be inviscid and attention is focused on the Hargneaves-Luke formulation, which consists of defining the functional as the work done by the pressure inside the fluid domain. Such a formulation allows the determination of all the most interesting field variables, namely the velocity, the pressure and the instantaneous and local shape of the moving surface.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
