Computational study of flow through a model glottis

A computational study to determine the dominant dynamic mechanisms in glottal airflow is presented.~ Computations of the flow through a scaled-up model of the human glottis were performed for f* = 0.035, 0.040, and 0.080, and a Reynolds number of 8000.~ Choice of boundary conditions is discussed. Comparison to available data (Krane, et al., JASA, 2007) is presented.~ Computed results are used to calculate dynamic relevance of momentum equation terms, and how this relevance varies with vibration frequency.~ The energy budget of the flow is also computed to show the dominant terms.
