Numerical Simulations Of Three Dimensional Glottis Flows

A detailed numerical investigation of the transient three d imensional flow downstream of the human glottis is performed . For the present work a threefoldly scaled up realistic stati c model of the vocal folds and a transient inflow function, whi ch is obtained from experimental data is applied to the CFD model. In the numerical simulations transient flow features like forming ring vortexes and axis switching are resolved which are also known for elliptical and rectangular jets. Similar structures can also be identified in the results of the time-r esolved PIV measurements. The influence of the ventricular f olds and the geometrical variation of the glottis contacts are al so considered in the numerical study. Copyright line will be provided by the publisher
