Numerical Simulation of Interaction of Fluid Flow and Elastic Structure Modelling Vocal Fold

摘要

This paper deals with an interaction of the viscous incompressible fluid flow with a simplified model of the human vocal fold. In order to capture deformation of the elastic body the arbitrary Lagrangian-Euler method is used. The linear elasticity model is considered. The problem is solved by the developed finite element method based solver. For the flow approximation the crossgrid elements are used. The motion of elastic structure is approximated by the piecewise linear elements. Numerical results are shown.
