Abstract
An axisymmetric lattice Boltzmann method has been developed to simulate pulsatile flow in circular pipes. First, the pulsatile flow in a circular pipe driven by sinusoidally varying pressure gradient with Womersley number α = 9.36, Re = 319 was studied. The numerical radial velocity agrees well with the analytical solution. Second, effect of Womersley number on pulsatile flow was investigated. The results demonstrate that the model is capable of handling axisymmetric pulsatile flow. Last, flow through pipes with various expansions was discussed.
