The Influence of Penalization Inlet Boundary Condition on the Stability Boundary
Original language description
The flow-induced vibrations of human vocal folds (VFs) are interesting and complex phenomenon with number of possible practical applications, see e.g. cite{Horacek2019tubes}, cite{MittalZhengBhardwajEtAl2011}. Mathematically it represents the fluid-structure interaction (FSI) problem which in this specific case poses many difficulties for numerical realization. One of the major difficulty is need to consider the flow domain time evolution especially during the closing phase, see cite{SvacekValasek2019collision}, followed by the question of a suitable inlet boundary condition, see cite{Svacek2017profily}, etc. % We present here the two-dimensional FSI model, see Fig.~ref{fig:FSIdomain}, where linear elastic problem is coupled to the incompressible Navier-Stokes equations in the arbitrary Lagrangian-Eulerian (ALE) form. The special attention is paid to the flow inlet boundary conditions (BCs), where the penalization boundary condition is introduced as a promising alternative to the usually used Dirichlet boundary condition or to the prescribed pressure drop between inlet and outlet.
