| Popis: |
The first aim of this paper is to compare three cases, where two cases contain turbulence sub-grid scale (SGS) models, which are commonly applied in wall-bounded flows. They use a bit different formulation of how to estimate the eddy-viscosity fields in a vicinity of walls. The SGS effect is obvious on flow rates through an intra-glottal gap. The second aim is to attend to a direct impact of the specific SGS model onto the sound pressure levels of frequency components (human formants). The third aim is focused on the effect of an initial time, when the vocal folds are in a start convergent phase itself and when the flow is suddenly accelerated due to boundary conditions. The effect is shown at aeroacoustic spectra. |
