This study proposes a method for mitigating the flow-induced vibration of a radial sluice gate to ensure operational safety and long-term stability. To this end, a supplementary plate was attached to the lower rear surface of the gate and its effect on vibration reduction is investigated using a fluid-structure interaction (FSI) analysis. Specifically, a three-dimensional finite-element method (FEM) model of the gate partially submerged in water was constructed and then validated by comparing the numerical responses of the gate with experimental results under the conditions of steady-state discharge. The FSI analysis showed that the vertical vibration acceleration of the gate diminished by 70% after the supplementary plate was attached, thereby reducing the swirling strength calculated from the vortex shedding behind the gate. The Strouhal number describing the intensity of the gate vibration in the flowing fluid was also reduced by 57% after the supplementary plate was attached. The results of this study can be used to inform the design and development of radial gates, as well as maintenance plans for their economical operation. ARTICLE HISTORY

“…For example, in the immersed boundary method, the FSI force is evaluated by using the Fréchet derivative of the elastic energy [14]. In the immersed finite element method, part of the force is calculated based on the stress tensor of the elastic structure that is determined by the material property [26].…”

We present a new computational framework for fluid-structure interaction problems that involve rigid body motion. Based on a partitioned strategy, the fluid and structural dynamics are computed separately, and the solutions communicate at the interface. The immersed boundary method is employed to handle the fluid-structure interaction, and the direct-forcing technique is utilized to calculate the interaction force. In particular, the rigid body motion is directly and explicitly incorporated into the formulation and computation of the structural dynamics. We demonstrate our methodology by numerically simulating the motion of single and multiple rigid circular discs interacting with nonlinear viscous flow.

“…FEM has eventually become an integral part or standard tool for design, synthesis and modeling process in virtually all-engineering sciences, such as, structures, thermodynamics, biomechanics, acoustics, materials, fracture mechanics, civil engineering, fault diagnosis and fluids dynamics etc (Borazjani, 2013;Bouaanani & Lu, 2009;Cheng, White, & Grosh, 2008;Dado & Shpli, 2003;Fiedler, Hosseini, Belova, Murch, & Öchsner, 2009;He & Kwan, 2001;Mackerle, 2004;Noack, Rolfes, & Tessmer, 2003;Smoljanović, Živaljić, & Nikolić, 2013;Tabiei & Wu, 2000;Wu, 2006;Zhang & Gay, 2007). However, during its application in different disciplines, preparations associated with discretizing intricate multidimensional geometries hinder its wide spread recognition as an analysis tool (Burkhart, Andrews, & Dunning, 2013;G.…”

An Adaptive Finite Element Analysis Integrated System supported through application of Case Based Reasoning (CBR) methodology is being proposed in this paper. The approach is fruitful for selection of an initial mesh from a library of solutions to initiate analysis process, as already tested optimal mesh will have lesser refinement iterations. The optimal mesh distribution, represented by object-oriented method, can be easily adapted to the topology of new problem in same domain. An integrated and universal structural analysis system models human reasoning by forming solutions through the retrieval and adaptation of successful strategies used in the past. Basic insight of two distinct subjects along with resolution of involved issues and integration strategy for development of an intelligent system is elaborated here. The research explains an algorithm for case retrieval and mesh generation procedures based on the principles of mapping method.
