We conclude that the flow field in the presented vocal tract model is of 3D unsteady nature and that it is important to consider in general the 3 dimensionality of the vocal folds. The main flow structures have been visualized. The aim of the continued study is the comparison of the flow fields of irregular cam cases, such as observed in medical practice against the regular convex cam case illustrated here. In particular the noise generation (acoustic sources) are extracted from the computed flow field such that the impact on the voice quality can be quantified and a possible pathology assessment will be feasible.
