Numerical Solution for Gate Induced Vibration Due to Under Flow Cavitation

Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...

A theoretical model on coupled fluid-structure impact buckling

A model simulating a coupledjuid-structure impact buckling phenomenon is constructed in this paper. Based on the experiment’,’ the model is designed as an impact system in which a small imperfection elastoplastic column is attached by its upper end to a large mass and by its lower end to aflatplate; it then perpendicularly impacts a viscous water free surface from a certain drop height or in a ...

NKS for Fully Coupled Fluid-Structure Interaction with Application∗

Newton-Krylov-Schwarz algorithms have been used in many areas and are often quite scalable and robust. In this paper we explore the application of Schwarz type domain decomposition preconditioners to some fully coupled systems for fluid-structure interaction. In particular, we are interested in developing a scalable parallel framework for the simulation of blood flow in human arteries [11]. In ...

Modeling Dynamic Production Systems with Network Structure

This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...
