Moving Load Analysis of Submerged Floating Tunnels
The concept of floating submerged tunnels becomes increasingly attractive idea to cross the straits. The structural solution in these bridges includes buoyancy force on tunnel body plus tension in mooring tethers. This paper investigates the effect of submergence on the dynamic response of submerged floating tunnels due to moving load. The inertial effect of the fluid on the submerged structure...
متن کاملTurbulent Flow in Wetlands with Submerged and Floating Vegetation
Turbulent Flow in wetlands with submerged and floating aquatic plants was studied by applying Boit’s poroelastic theory to turbulent flow. The velocity distribution formulas were described by solving the modified Bessel equations. The effects of plant porosity and turbulent coefficient on the velocity distribution, shear stress distribution and energy relations were analytically derived. Severa...
متن کاملA photogrammetric approach to survey floating and semi-submerged objects
The article presents an innovative methodology for the 3D surveying and modeling of floating and semi-submerged objects. Photogrammetry is used for surveying both the underwater and emerged parts of the object and the two surveys are combined together by means of special rigid orientation devices. The proposed methodology is firstly applied to a small pleasure boats (approximately 6 meters long...
متن کاملExperimental Investigation on the Deviated Sediment and Flow to Sediment Bypass Tunnels (SBTs) Using Submerged Plates
Sediment Bypass Tunnels (SBTs) are deviant channels that convey the current containing sediments from the upstream of the reservoir to the downstream of the dam. In this research, by applying submerged plates on the entrance of a 90-degree diversion channel for sediment transport, the effect of hydraulic parameters of flow and changes in the angle of plates on sediment transport and deviated fl...
متن کاملScale-Model Experiments for the Surface Wave Influence on a Submerged Floating Ocean-Current Turbine
In order to harness the kinetic energy of marine currents, we propose a novel ocean-current turbine with a horizontal axis. The turbine can be moored to the seabed and function similarly to kites in a water flow. To operate such turbines in a marine current, the resulting rotor torque needs to be canceled. Therefore, the proposed turbine is designed with a float at its top and a counterweight a...
