Numerical and experimental exploration of flow through a teeth-shaped nozzle
An asymmetrical constricted rectangular nozzle is designed representing upper incisors in the oral tract. Steady flow through the nozzle is studied for a fixed constriction degree of 70% and bulk Reynolds number Re b =4000. Flow data are obtained numerically by Large Eddy Simulation as well as exper...

| description | An asymmetrical constricted rectangular nozzle is designed representing upper incisors in the oral tract. Steady flow through the nozzle is studied for a fixed constriction degree of 70% and bulk Reynolds number Re b =4000. Flow data are obtained numerically by Large Eddy Simulation as well as experimentally from smoke visualisation and from Particle Image Velocimetry. Quantitative and qualitative exploration of the mean and fluctuating properties of the flow field reveals the impact of the obstacle’s presence on the overall flow field and stresses the need for future in depth studies of the impact of geometrical parameters. |
