Simulation of Unsteady Compressible Flow in a Channel with Vibrating Walls - Influence of the Frequency

Original language description

This study deals with the numerical solution of a 2D unsteady flow of a compressible viscous fluid. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall. The channel is a simplified model of the glottal space in the human vocal tract. The flow is described by the system of Navier-Stokes equations for laminar flows considered in the Arbitrary Lagrangian-Eulerian form. The numerical solution is implemented using the finite volume method and the predictor-corrector MacCormack scheme with Jameson artificial viscosity using a grid of quadrilateral cells. The numerical results for unsteady flows in the channel are presented for inlet Mach number M = 0.012 , Reynolds number Re = 4500 and the wall motion frequency 20 and 100 Hz.
