Title: | High resolution ship hydrodynamics simulations in opens source environment | Authors: | Del Puppo, Norman | Supervisore/Tutore: | Piller, Marzio | Issue Date: | 16-Apr-2015 | Publisher: | Università degli studi di Trieste | Abstract: | The numerical simulation of wake and free-surface flow around ships is a complex topic that involves multiple tasks: the generation of an optimal computational grid and the development of numerical algorithms capable to predict the flow field around a hull. In this work, a numerical framework is developed aimed at high-resolution CFD simulations of turbulent, free-surface flows around ship hulls. The framework consists in the concatenation of “tools” in the open-source finite volume library OpenFOAM®. A novel, flexible mesh-generation algorithm is presented, capable of producing high-quality computational grids for free-surface ship hydrodynamics. The numerical framework is used to solve some benchmark problems, providing results that are in excellent agreement with the experimental measures. |
