3D GPU SPH analysis of coupled sloshing and roll motion

Abstract

The coupled roll motion response of a single degree of freedom system to which a passive anti-roll tank has been attached is considered and its performance studied numerically with a 3D GPU SPH code, aimed at simulating the sloshing flows occurring inside the tank. Results are compared with experiments from Bulian et al. (2010), in which 2D simulations were also presented. Progress achieved thereafter is documented, mainly consisting in the implementation of a parallelized solver that runs on a GPU card, which allows the simulation of low resolution 3D and high resolution 2D computations.
