Interaction between structures and fluids
Abstract
A finite element model for the study of solid-fluid interaction, with applications in flow-induced vibration analysis of reactor vessel and heat exchanger internals, is presented. Plane triangular finite elements for fluid, solid and solid-fluid continua and equivalent mass, damping and stiffness matrices and interaction load array were developed for the study of wave propagation phemonena in a two-dimensional flow field. This is verified by solving a wave propagation flow problem consisting of water, between two elastic parallel plates, initially at rest and accelerated suddenly by applying a step pressure at one end.
