Interaction between hydraulic conditions and structures – fluid structure interaction problem solving. A case study of a hydraulic structure

Bernard Twaróg

Abstrakt

Contemporary analytical and computational techniques enable the researcher to define interaction between varying flow rates, varying volumes of filling water and the deformation and stresses occurring in the structural components of a hydraulic structure. This study aims to describe and create visualisations, under selected operating conditions, of displacements, deformations and stresses of a hydraulic structure resulting from loads generated by hydraulic conditions in standard components of the structure. A sample analysis was carried out for the Niedów earthen dam on the Witka River that failed in 2010 due to a disastrous inflow. The scope of this analysis covers the components of the spillway section: the spillway monolith, the dissipation basin slab and the flip bucket. The results of analytical work and visualisations are shown using the Flow3D software program.
