Sažetak
The paper describes a numerical method for the coupled simulation of fluid flow and motion of floating bodies with ap-plication to high-speed vessels. The main characteristics of the method are: finite-volume approach based on arbitrary polyhedral control volumes which can move and deform during simulation ; overset grids to allow arbitrary motion of floating bodies (including capsizing) ; high-resolution interface-capturing scheme (“volume-of-fluid” approach) which allows simultaneous computation of water and air flow and accounting for wave overturning, trapped air in water and water drops in air ; cavitation model based on bubble-dynamics approach that allows prediction of vapour production around body parts where pressure drops below saturation level and bubble collapse in zones of higher pressure. Two application examples are presented: a validation study with a patrol vessel moving over a wide range of Froude numbers, and a demonstration of practical use of simulation to design and optimize the winning boat for the America’s Cup 2013.
