Abstract
The upcoming paper brings forward some remarks connected with a turbulence initialization at the inlet of a computational domain. The computational domain is a simplified model of human larynx with vocal folds. As a numerical solution of an airflow through the larynx is applied a Large-Eddy Simulation (LES) approach. Our goal was to induce turbulence fluctuations directly in the subglottal area by using a model of a turbulence grid at inlet. The Reynolds numbers encountered in glottal flow lie in the transitional regime.
