Investigating 2D Fluid Dynamics after the Ship-Bridge Pier Collision by Numerical Simulation

LUO Xiongping The Faculty of Mechanical Engineering and Mechanics,Ningbo University,Ningbo 315211;  
A 2D process of a plane-movement object(boat) moving around a static one(bridge pier) is investigated by combining incompressible Navier-Stokes equations with immersed boundary methods.The fluid’s effects on the boat and the boat’s track are mainly studied.The results show that the drag and lift curve lines oscillate with finite amplitudes at the beginning and approach to periodic micro vibrations soon.The boat rotates clockwisely at first,and then the speed becomes smaller and smaller,and later it changes to an anticlockwise rotation.Finally the boat’s stern moves away from the pier,and it won’t impact with the pier.The boat’s trajectory agrees with that from the real boat experiments.
