Abstract
The hydrodynamic interactions between successive two-dimensional (2D) solitons and structures have been investigated based on velocity potential theory. Successive solitons are generated by a moving horizontal elliptic cylinder at critical speed in shallow water. As a submerged cylinder or a rectangular floating barge encounters the solitons, it drifts with the wave induced flow. The interactions of solitons and structures are simulated using the mixed Euler-Lagrangian method (MEL) through a time stepping scheme. The auxiliary functions are introduced to analyse the coupled motions. The responses of structures have been analyzed and the velocity fields have been examined.
