Froude Number and Scale Effects and Froude Number 0.35 Wave Elevations and Mean-Velocity Measurements for Bow and Shoulder Wave Breaking of Surface Combatant DTMB 5415

This study is a good demonstration on how complementary EFD and CFD can provide a powerful and advanced tool in analyzing complex industrial flows. Results are presented from a cooperative study between INSEAN and IIHR about wave and flow field measurement about a surface combatant with focus on the 3D ship wave breaking. At Fr-0.35, free-surface near and far fields have been measured, as well as the velocity in some transversal planes under the bow and shoulder wave. CFD computations have also been used to complete and extend EFD data and to understand some particular features of the flow, such as location of vortices near the free-surface and scars.
