... ABSTRACT An experiment on the interaction of an internal solitary wave (ISW) with a horizontal cylinder was conducted in a gravitationally stratified fluid flume. The particle image velocimeter (PIV) and the force sensor were used to study the flow structure and the forces on the cylinder...

...). The paper addresses the transfer of loads between the rigid walls of a mobile liquid containment system and the liquid via an inflatable device and vice versa. The options of transferring loads are primarily dependent on the geometry of the liquid containment system and may vary from a horizontal cylinder...

Applying continuum fluid mechanics for a simulation approach, Euler and Navier-Stokes solvers provide a time accurate simulation only if an appropriate free surface determination and propa- gation is implemented...

... Horizontal cylinders are popular components of offshore structures such as offshore pipelines and oil platforms. The wave and current loads are the primary loads acting on the offshore structures. The research on the hydrodynamic forces acting on the horizontal cylinders is of important engineering...

Two test cases leading towards simulation of the full dynamics of Pelamis and the Manchester Bobber have been modelled using different CFD techniques. The problems involve the interaction between regular waves and fixed horizontal cylinders...

INTRODUCTION The problem of waves diffracted by a submerged horizontal cylinder whose axis is parallel with the wave crests is one that is of both industrial and intrinsic interest. The existence of linear and second order analytical solutions...
