Numerical simulation of the movement behavior of floating structures

Abstract

The sea level is rising, and floods threaten the infrastructure all over the world; therefore, we should identify the risks for envelops of buildings and settlements. The risks arise due to the new boundary conditions and a direct contact between the water flows in motion. A floating construction site requires a manifold adaptation of structures. The paper demonstrates the effect of water waves on floating houses built on abandoned open pit mines. Pictures of destroyed accessways to such properties have proven the need to study the effect of water waves on floating houses. In order to minimize the time and spending on experimental activities, some of the field studies should be replaced by numerical simulations using modern computing equipment and ANSYS FLUENT, ANSYS MECHANICAL FSI, and ANSYS AQWA software. The results can be validated using a hydraulic testing channel (15 x 5 m), a floating platform near the harbor of Lake Gro r schener See and floating houses in the Lusatian Lakeland. The results demonstrate the wave forces acting on the structures of the pontoons. New connection elements, adapted versions of materials and structures have been developed, water waves are damped, and options for the wave energy use have been analyzed.
