Numerical and experimental exploration of flow through a teeth-shaped nozzle
MetadataShow full item record
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.

Secondary Flow Vortex Structures and Forced Convection Heat Transfer in Fluid Flow through Curved Elliptical DuctsChandratilleke, Tilak; Nadim, Nima (2014)Fluid flow through curved ducts is essentially characterised by the secondary flow effects due to duct curvature and cross-sectional flow geometry. Such flows produce vortex structures making the fluid behaviour vastly ...
Nadim, Nima (2012)Fluid flow through curved ducts is influenced by the centrifugal action arising from duct curvature and has behaviour uniquely different to fluid flow through straight ducts. In such flows, centrifugal forces induce ...
