In this article, effect of a time-dependent stenosis on the flow of a non-Newtonian fluid through porous medium in axially symmetric constricted tube is analyzed using integral method. The study is based on a second grade fluid model. An order of magnitude analysis is performed to simplify the model for mild constriction. Integral approach coupled with the fourth-order polynomial solution for the...
This paper studies the unsteady MHD flow of a viscous fluid in which each point of the parallel planes are subject to the non-torsional oscillations in their own planes. The streamlines at any given time are concentric circles. Exact solutions are obtained and the loci Γ of the centres of these concentric circles are discussed. It is shown that the motion so obtained gives three infinite sets of exact...
