Analysis on interaction between block of water and vertical large span gate

Abstract

Fluid Structure Interaction (FSI) is one of the emerging areas of numerical simulation and calculation that many researchers pay more attention in recent years. In general, although a considerable number of FSI studies exist, the numerical prediction of free surface cause tidal in the fields of fluid to gate is challenging. One of the main difficulties in a numerical method for this simulation is the modeling the interaction between fluid and gate where the dynamic response can transfer nature on gate to obtain the dynamic response of gate such deflection and stress during tidal propagation. The analysis is completed in 3D with a help of commercial ADINA-FSI softwave (Bathe. K.J, 2012) in which 3D modal is similar to structure of Muong Chuoi project with the main pipe truss seat on the side of the sea. The dynamic response impact on gate is based on the tidal wave characteristic in Mekong delta river.
