Comparison of streamwise velocity (U) profiles for the baseline models. The approximate location of the line profiles in the oropharynx, VP valve, and the nasopharynx are indicated in the small image to the left. Velocity profiles are normalized with the maximum velocity (Umax = 3.2 m/s and 29.4 m/s for the experimental and numerical data, respectively). The span of each profile is normalized by its length (D) where y/D = 0 is on pharyngeal wall and y/D = 1 is on the velar wall.
