Numerical Simulation of Interaction of Fluid Flow and Elastic Structure Modelling Vocal Fold
J. Valášek, P. Sváček, J. Horáček
pages 338 - 339, full text

This paper deals with an interaction between the fluid flow and an elastic body. A simplified model of the human vocal fold is considered. In order to capture deformation of the elastic body the arbitrary Lagrangian-Euler method (ALE) is used. The viscous incompressible fluid flow and linear elasticity models are considered. The problem is solved by the developed finite element method (FEM) based solver. Particularly, for the flow approximation the crossgrid elements are used, whereas for the elastic structure the piecewise linear elements are employed. Results of numerical experiments are shown. Mathematical model For the sake of simplicity our study is restricted to a 2D model problem. A scheme of the used model is shown in Figure 1, where Ωsref is the reference representation of the structure and Ωfref denotes the domain of the fluid.
