NUMERICAL AND EXPERIMENTAL ASSESSMENT OF THE TOTAL RESISTANCE OF A YACHT

One of the main goals ship design process is reduction total resistance, which nowadays even more highlighted due to increasingly stringent rules related energy efficiency. In this paper, investigation impact bow on resistance a yacht carried out for three models by towing tank tests and numerical simulations. The verification validation studies are performed, satisfactory agreement achieved. Also, comparison turbulence prediction made. flow around analysed it demonstrated that bulbous causes wave elevations. Experimental results indicate decrease in can be up 7%. Finally, applicability CFD within presented.
