Dynamic Analysis of a Gate–Fluid System

Abstract

The dynamic behavior of hydraulic gates needs to be determined for design purposes. This is a difficult task because the interaction between fluid and gate can significantly affect the response of the structure and hence has to be properly taken into account in the analysis. The goal of the present work is to use a velocity potential-based finite element formulation and a hydraulic model test for dynamic analysis of a radial gate–fluid system. The problem is solved using the displacement and velocity potential as the variables in the solid and fluid domain, respectively.
