Description 610-616
In this paper, the unsteady flow of Newtonian fluid through a curved pipe due to a pulsatile pressure gradient has been
considered. The flow is three dimensional and the partial differential equations governing the flow are highly coupled and
non-linear. Approximate analytical solutions of the governing partial differential equations have been obtained without
neglecting any term containing the curvature ratio. Perturbation series in terms of curvature ratio has been used for obtaining
the solutions. It is interesting to note that the solutions are valid for large as well as small values of Womersley number. The
effect of different parameters such as, Reynolds number, Womersley number and curvature ratio on the flow through curved
pipe is discussed in this paper. It is found that the axial velocity is qualitatively periodic in nature, as expected. The
Reynolds number and curvature ratio are found to shift the axial velocity towards the outer boundary of the curved pipe.
