- W2393321897 abstract "In order to overcome the difficulties of the large amplitude motion of floating body in fluid field and to compute wave profile and forces acting on solid body more accurately,ALE(arbitrary lagrangian-eulerian) method was used to build the mathematical model of fluid-solid coupled motion with free surface.The dynamic grid was applied to tracking the motion of the floating body.The adaptive grid was utilized to fine the grids near the free surface.The motions of floating body coupled with inviscid and viscous fluid were calculated and compared with the analytical ones from spring-object vibrating model.The swaying with initial list angle of the floating body coupled with viscous flow was also computed.The results show that the heaving of the floating body in inviscid flow well agrees with the one from the spring-object vibration model.In viscous flow,the agreement between the heaving of the floating body and the practical one was sound because it was the damping vibration,and the angle of list decreased with the time.The list vibration of the floating body well agrees with the one from the theory in the case of small angle.The results show that the computational program is reliable and accurate.The job laid a foundation for application of ALE method to analyzing fluid-multibody coupled motion in the future." @default.
