Fig. 2.

Fluid movement q (red arrows) during one oscillation cycle (0–5 milliseconds for a fundamental frequency of 200 Hz) in the coronal plane (Top) and on the medial surface along the anterior-posterior direction (Bottom) in the case with water resupply. The top panel also shows the color-coded contour lines of the percentage local water loss relative to the initial state (1−ζ). B2VF velocity and VF2M velocity refer to the fluid movement from blood vessel to vocal fold body and from vocal fold body to surface liquid layer, respectively. The vertical dashed lines in the top panel indicate the glottal midline.
