Numerical Simulation for FreRolling Motion of a Surface Vehicle
To study seakeeping capacity of a special surface vehicle,free rolling motion in static water is investigated; damping coefficient and rolling moment of inertia was taken as criterion; a mathematical model for 6-dof motion of the vehicle in viscous flow is constructed based on N-S equations and rigid body space motion equations.Forces and moments induced by flow around vehicle are computed from cells of surface on the vehicle.Local remeshing scheme is taken to remesh the field when position of the vehicle changed.Surface of vehicle is taken as non-slip wall boundary.Results indicate that damping coefficient and rolling moment of inertia deduced form computation coincide with experimental results.
