On the problem of singular limit
Caggio, Matteo ; Ducomet, B. ; Nečasová, Šárka ; Tang, T.
We consider the problem of singular limit of the compressible Euler system confined to a straight layer Ωδ = (0, δ)×R², δ > 0. In the regime of low Mach number limit and reduction of dimension the convergence to the strong solution of the 2D incompressible Euler system is shown.
Numerical experiment of flow Mach in vocal tract
Pořízková, P. ; Kozel, K. ; Horáček, Jaromír
This study deals with the numerical solution of a 2D unsteady flow of a compressible viscous fluid in a channel for low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall, nearly closing the channel during oscillations. The channel is a simplified model of the glottal space in the human vocal tract. The flow is described by the full system of Navier-Stokes equations or by adiabatic system equations.
