Whole-field 3D Characterization of a Pulsating Jet using Synthetic Aperture Particle Image Velocimety

Utah State University

In this study synthetic aperture particle image velocimetry is used on an excised human vocal fold model to study the airflow over the vocal folds during voice production. For the first time, a whole-field, time-resolved, 3D description of the flow is presented over one cycle of vocal fold oscillation. Complex, unsteady, 3D flow behavior is observed as the jet evolves.
