Abstract
This paper demonstrates techniques for modelling fluid-structure interactions using COMSOL Multiphysics v 4.2a, which illustrates how to solve for the flow in a continuously deforming geometry using the Arbitrary Lagrangian-Eulerian (ALE) technique and corresponding deformation, displacement analysis. The present work reports the computation of the deformation and displacement in structure along with the fluid flow in a continuously deforming geometry, for different types of structures like circular, rectangular, ellipse, which are placed inside of the flow channel as an obstacle. Fluid structure interaction between wind and sails, modelling of parachutes, fluid structure thermal calculation, stability and response of aircraft wings, the flow of blood through arteries, response of bridges and tall buildings to winds, prediction of aero elastic parameters in military aircrafts, vibration of turbine and compressor blades and the oscillation of heat exchangers can also be analysed using this method
