IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

EXPERIMENTAL INVESTIGATION INTO THE EFFECTS OF FLUID-STRUCTURE INTERACTION ON THE SLOSHING WAVES IN 3D ELASTIC TANKS
Author : CHENGUANG LI , MEIRONG JIANG , BING REN , YONGXUE WANG
The flexible walls of the liquid container will deform under the sloshing loads. The deformation has a significant influence on the hydrodynamic behavior of the sloshing in the tank. A model test is conducted to study the hydro-elastic effect on the sloshing waves in the elastic square tank. The experimental liquid depth h/L is 0.16,The model tanks are exited in 1-D harmonic longitudinal motion and the excitation frequency is in the vicinity of the lowest natural frequency of the liquid. Due to the influence of the fluid-structure interaction, the lowest natural frequency of the liquid in the elastic tank slightly deviates from that in the rigid tank of the same size. The wave shapes and amplitudes in the rigid and elastic square tanks are classified and analyzed under the 1D harmonic longitudinal excitation with different excitation frequencies. Corresponding to the different wave regimes of the two-dimensional traveling waves, transition state, three-dimensional resonance and the secondary resonance, the free surface elevations are compared between the rigid tank and the elastic tank to investigate the effect of fluid-structure interaction.
