| Abstract | With the rise of computational developments came along the possibility to perform high- quality computational fluid dynamics (CFD) simulations. Where the resistance and propul- sion forces of ships used to be determined through the use of empirical formulas or by up- scaling model experiments, the computational power is now available to calculate full-scale resistance forces and propulsion thrust in a direct manner. While there are many validation cases available for CFD on model ships by comparing numerical results to forces measured in a towing tank, there is a lack of CFD validation cases on full-scale vessels as (almost) no experimental data is available for comparison. Through recent developments, there is now a set of experimental data available on the full-scale MV Regal vessel, as well as a set of full-scale CFD results from the JoRes project. The goal of this thesis is to set up a working environment in OpenFOAM, an open-source CFD toolbox, for hull resistance and open-water propeller tests. While there are still many adjustments that can be made, the resulting configuration of this study can be used as a starting point for further full-scale CFD assessments, especially because there are currently no available full-scale validation cases using open-source software. |
