The paper compares two approaches for solution of the unsteady airflow in human vocal folds: a 2D finite element model (with optional vocal fold oscillation) and a 3D finite volume computation (with optional turbulence model). The equations are solved using open-source libraries. The results show that the 3D flow effects are significant, particularly further downstream glottis.
