In this paper, effect of a bottom Air Circulating Tank (ACT) on hydrodynamic performance of a hull investigated by using a commercial Computational Fluid Dynamics (CFD). Firstly, hydrodynamic performance as the resistance acting on an original hull was computed by the CFD and compared with those of the experimental data to validate the CFD results. Secondly, a new hull with proposed bottom ACT had been computed and compared with the results of the original hull. From obtained results of the pressure distribution around hull and resistance acting on the hull were shown, the effects of the ACT on hydrodynamic performance of the hull were found. More ever, the target of this study is that understanding what happened in the ACT and how improving hydrodynamic performance of a hull with an ACT.

摘要

In this paper, effect of a bottom Air Circulating Tank (ACT) on hydrodynamic performance of a hull investigated by using a commercial Computational Fluid Dynamics (CFD). Firstly, hydrodynamic performance as the resistance acting on an original hull was computed by the CFD and compared with those of the experimental data to validate the CFD results. Secondly, a new hull with proposed bottom ACT had been computed and compared with the results of the original hull. From obtained results of the pressure distribution around hull and resistance acting on the hull were shown, the effects of the ACT on hydrodynamic performance of the hull were found. More ever, the target of this study is that understanding what happened in the ACT and how improving hydrodynamic performance of a hull with an ACT.
