THE LATTICE-GAS METHOD AND INTERACTION WITH AN ELASTIC SOLID

The aim of this paper is to illustrate the possibility of simulating f luid-structure interactions by a lattice gas method. After a brief rev iew of lattice gas hydrodynamics, this paper presents a method for eva luating the displacement of the nodes of the structure, the flow, and the technique used to link the two descriptions. The realization of th e kinematics condition at the moving interface is explained in detail. The paper is concluded by two examples: free vibrations of a beam in a closed box filled with a fluid, and free vibrations of a beam in a c hannel flow. (C) 1996 Academic Press Limited
