Fluid-structure interaction in human vocal folds

Abstract : The velocity and pressure fields in the proximity of the vocal folds were studied by means of numerical modelling and experimental investigation. The mathematical model, based on the 2D incompressible Navier-Stokes equations in arbitrary Lagrangian-Eulerian formulation discretized by the finite element method, was programmed in the Fortran language, using numerical library Mélina. The results of the numerical simulations schow the development of the supraglottal jet and evolution of the recirculation vortices within one vocal fold oscillation cycle. The physical model, scaled 4:1, yields the acceleration, supraglottal pressure and acoustic signals emitted by an elastic body vibrating in the wall of a wind tunnel due to coupling with the flow. The velocity fields in the supraglottal domain wee measured on this model by a PIV system synchronized with the vibration.
