Experimental and Numerical Hydrodynamic Analysis of a Planing Hull Pleasure Boat

摘要

The work addresses a critical analysis on the hydrodynamic of a high speed planing hull by carrying out towing tank tests and URANSe campaign. Towing tank tests have been performed by ITTC'57 standards. Computational Fluid Dynamics (CFD) has been solved by using an overset block, in order to avoid the morphing grid, during 2 degree of freedom motions. Numerical results have matched experimental data with high accordance and allow to obtain crucial information that the tests in a model basin can hardly provide, as, for example, the true wetted surface in planing phase. A critical discussion of the results has been performed.
