Numerical Flow Simulation
This initial report serves as a background structure for the later final report. It does not claim to be complete, as it only demonstrate that the chosen mesh and physical models are verified, and just need to be refined before the post-processing.
When a boat hull is set into motion on still water, it generates a wave pattern, resulting in the creation of a wave drag opposing the boat motion. The Wigley hull is a simplified parabolic boat geometry, defined analytically. It has been studied a lot, both experimentally and numerically, in various flow conditions. That’s why it is used to provide verification and validation when testing a new numerical simulation algorithm for example.
(Kajitani 1983) gives measured physical quantities obtained during various experiments on different sizes of the Wigley hull, especially on one of the same size as the one studied in this report. This paper will be useful to validate our computed data.
