abstract = {<p style="text-align: justify;">Numerical simulations have been carried out for laminar sinusoidal pulsating
flow in a tube with smooth single constriction. A second-order finite volume
method has been developed to solve the fluid flow governing equations on a nonstaggered
non-orthogonal grid. The effects of the Reynolds number, the Womersley
number, the pulsatile amplitude, the constriction ratio and the constriction length on
fluid flow in constricted tube will be investigated. It will be demonstrated that the
dynamic nature of the pulsating flow greatly depends on the frequency of the flow
changes. It is observed that the peak wall vorticity seems to increase with the increase
of Reynolds number, the pulsating amplitude and the constriction ratio. The
peak values of instantaneous wall vorticity are not greatly affected by the variation of
Womersly number. The constriction length does not put a significant impact on the
flow instantaneous streamline behaviors compared with other parameters. However,
the peak wall vorticity increases monotonically with the decrease of the constriction
length.</p>},
