... shows that both the non-uniform pressure distribution together with the viscous stress along the pipe periphery and the pressure-drop along the seabed are formed synchronously due to the existence of the pipe. The former will generate the hydrodynamic forces on the pipe, which may trigger the lateral...

... Abstract The numerical investigation of the passive hydrodynamic performance of the manta ray beneath the water surface is presented. The main aim is to investigate the effect of attack angle on hydrodynamic forces of the manta ray near the water's surface. Three dimensional incompressible...

... of the study, two vortex methods, the Random-Walk method and the Core-Spreading method, are applied to vertical oscillating plate under free surface. Hydrodynamic forces on the plate are calculated and compared with experimental results. INTRODUCTION It has been required that the ocean space is effectively...

... ABSTRACT: The hydrodynamic force acting on a fin oscillating beneath a free surface is investigated. To safely utilize floating structures under severe environmental conditions in the sea, the motion of the floating body and the mooring forces acting on the body should be reduced. To decrease...

... forces such as the hydrodynamic force of seawater, the buoyancy forces acting at discrete locations on the flexible hose, and other forces are considered. The virtual prototypes of each subsystem are modeled and connected to form the complete integrated mining system and the interaction models between...

... forward speed. Therefore, it can be safely said that the phenomena occur only when hydrodynamic forces are dominant comparing with hydrostatic forces like buoyant forces. Then, the phenomena are generally referred to as dynamic instabilities (Blount & Codega, 1992). Although the phenomena are dynamic...

... manoeuvrability prediction requires amongst other things, knowledge of the ship resistance and propulsion characteristics. Part of the resistance arises from the hydrodynamic forces acting on the ship body moving at a constant speed in calm seas. The hydrodynamic force computation is further complicated...
