The streamlines of the horizontal component of the Kirchhoff vector and the vortex sheet at 1/2 of the vocal fold cycle, when the vocal folds are maximally open (a) for the case when there are only vocal folds and (b) for the case with ventricular folds.

Gradient of the axial Kirchhoff stream function projected onto the vortex convection direction (-axis) as a function of position of the elements of the vortex sheet at 1/2 of the vocal fold cycle (a) for the case when there are only vocal folds and (b) for the case with ventricular folds.

FIG. 7.

Vortex sheet at shown with outlines of the top of the vocal folds and the ventricular folds at 1/6 intervals of the second glottal cycle. The columns of panels on the left are during the opening phase, sequenced from top to bottom. The columns on the right are during the closing phase, sequenced from top to bottom. The -axis has been magnified with respect to the -axis.
