Numerical Modeling of the Forced Motion Dynamics of Antiroll Tank With OpenFOAM

The aim of this work is to approach the full design of an anti-roll tank through numerical simulation, looking for the way to minimize the computational cost. The results have been validated with experiments from a rectangular tank, a tank with a C-shaped section and a rectangular tank with baffles. These tests were performed for 3 and 6 degrees of roll, and for different levels of water inside. The Open Source Computational Fluid Dynamics (CFD) tool OpenFOAM has been used to carry out the simulations and to validate the numerical model. We have worked in 3D testing different turbulence models (laminar, k-ε, k-ω, k-ω SST) and different boundary conditions (fixed values or slip). Convergence analyses of different meshes have also been performed. After filtering the outcomes, it is shown that the model k-ω SST with slip boundary estimation is the most reliable model.
