四、报告题目：Computational Modeling of Tsunami Loading on Structures Considering Fluid-Structure Interactions

报告摘要：

Tsunamis, such as the 2004 Indian Ocean, 2010 Chile, 2011 Japan, and 2018 Sulawesi ones, have caused hundreds of thousands of casualties and widespread damage to coastal infrastructure. This seminar presents a three-dimensional (3D) numerical model developed to simulate the tsunami propagation and the hydrodynamic loading on structures. It solves the Navier-Stokes equation using a finite volume method with VOF (volume of fluid) capability. The 3D flow model has been coupled with a structural model to simulate the response of structures subjected to tsunami or other types of impulsive wave loading. The structural motion is fed back into the fluid solver via a technique that combines a sharp interface immersed boundary method with the cut-cell method. The fully coupled simulations show that the restoring force patterns heavily depend on the structural dynamics. Without considering the fluid-structure interactions, the model exhibits large errors in the magnitude and period of restoring force in the structure.
