We have examined the peristaltic flow of Carreau fluid in a rectangular channel through a porous medium. The governing equations of motion are simplified by applying the long wavelength and low Reynolds number approximations. The reduced highly nonlinear partial differential equations are solved jointly by homotopy perturbation and Eigen function expansion methods.

The expression for pressure rise is computed numerically by evaluating the numerical integration.

The physical features of pertinent parameters have been discussed by plotting graphs of velocity, pressure rise, pressure gradient, and stream functions.

1. Introduction

Investigation of flow through a porous medium has many applications in various branches of science and technology. The applications in which flow through a porous medium is mostly prominent are filtration of fluids, seepage of water in river beds, movement of underground water and oils, limestone, rye bread, wood, the human lung, bile duct, gallbladder with stones, and small blood vessels which are few examples of flow through porous medium1.

Peristaltic mechanism is another important phenomenon which has exploited the attention of many researchers due to its physiological and industrial applications. A large amount of literature is available on the peristalsis involving Newtonian and non-Newtonian fluids with different flow geometries2–12. The peristaltic flow through a porous medium has been also discussed by number of researchers. Pandey and Chaube13have examined the peristaltic flow of micropolar fluid through a porous medium in the presence of external magnetic field. They pointed out that the maximum pressure is strongly dependent on permeability

the peristaltic transport of a power law fluid in a porous tube. In another paper Mishra and Rao16have studied the peristaltic transport in a channel with a porous peripheral layer.

Some other papers on this topic are given in the references17–20. The mathematical model of peristaltic flow in a two-dimensional symmetric and asymmetric channel was discussed by Eytan and Elad17because of its application in interuterine fluid flow in a nonpregnant uterus. A number of researchers have examined the peristaltic flow of two-dimensional flow in an asymmetric channel18–25. However Reddy et al.26have recently given the idea that the sagittal cross-section of the uterus may be better approximated by a tube of rect- angular cross-section than a two-dimensional channel and presented the influence of lateral walls on peristaltic flow in a rectangular duct. Only few papers two or threehave been given in literature which discuss the peristaltic flows in a rectangular channel26,27.

Motivated by the previous studies, in the present investigation, we have examined the peristaltic flow of Carreau fluid in a rectangular symmetric channel through a porous medium. In the laboratory frame under the assumptions of long wavelength and low Reynolds number, the solutions of the governing equations of Carreau fluid in a rectangular duct have been found by using homotopy perturbation method. The physical features of the pertinent parameters are discussed by plotting pressure rise, velocity, pressure gradient, and stream functions.

2. Mathematical Formulation

Consider the peristaltic flow of an incompressible Carreau fluid in a duct of rectangular cross-section through a porous medium having the channel width 2dand height 2a. We are considering the Cartesian coordinate system in such a way thatX-axis is taken along the axial direction,Y-axis is taken along the lateral direction, andZ-axis is along the vertical direction of rectangular channel.

The peristaltic waves on the walls are represented as ZHX, t ±a±bcos

λ X−ct

, 2.1

whereaandbare the amplitudes of the waves,λis the wavelength,cis the velocity of the propagation,tis the time, andX is the direction of wave propagation. The walls parallel to XZ-plane remain undisturbed and are not subject to any peristaltic wave motion. We assume that the lateral velocity is zero as there is no change in lateral direction of the duct cross- section. LetU,0, Wbe the velocity for a rectangular duct. The governing equations for the flow problem are stated as follows.

4. Results and Discussions

In this section, we have discussed the homotopy perturbation solution given in 3.12 through plotting the graphs for velocity, pressure gradient, pressure rise, and stream lines. In Figures4aand 4b, the velocity field is plotted for different values of flow rateQ, both for two dimensional and three-dimensional flows, respectively. It is observed that with the increase of flow rateQ, the velocity field decreases. The variation of velocity field for different values ofβ is displayed in Figures5aand 5b. It is seen that with the increase in β, the velocity field decreases, and the maximum velocity is at the centre of the channel for small values ofβ. In Figures6aand6b, the velocity field increases with the increase inφ. How- ever, with the increase ink, the velocity field decreases near the channel wall and increases in the middle see Figures 7a and 7b. The velocity field distributions for different

values of We and n are shown in Figures 8 and 9. It is seen that the magnitude of velocity increases for different values ofWe, while decreasing forn. The pressure gradient graphs for various values of Q, β, φ, and k are plotted in Figures 10, 11, 12, and 13.

It is observed that with the increase in Q and k, the pressure gradient decreases but increases with β and φ, and the maximum pressure gradient occurs in the middle of the channel for small values of the parameters. It means that flow can easily pass in the centre of the channel. The plots for pressure rise Δp for different values of β, φ, and k are portrayed in Figures 14, 15, and 16. It is seen that pressure rise increases with the increase in β in the peristaltic pumping region; that is, when Δp > 0, Q < 0Q ∈

−2,0 and in the augmented pumping region Q ∈ 0,2, the pressure rise decreases see Figure 14. The pressure rise increases with the increase in φ in the region Q

−3,0.6 and gives opposite behavior in the region 0.6,3 see Figure 15. In Figure 16, it

in Figures 17,18, and19. The stream lines for various values ofβ are shown in Figure 17.

It is seen that the trapping bolus decreases with the increase inβ, while size of the bolus is reduced withβ. The stream lines for different values ofφandk are sketched in Figures18 and19. It is depicted that with the increase in both parameters, the numbers of trapping bolus increase. It is also noted that bolus becomes small in size forφbut enlarges for the parameter k.

Tables1and2are placed to compare the present work with26. Figures2and3are drawn according to the data given in Tables1 and 2. From these figures it is clear to see that the analytical solution is in good agreement with the exact solution. Also, it is observed that velocity is reduced in the case of non-NewtonianCarreaufluidseeFigure 1. From Figure 2, it is seen that pressure rise is increased for the present fluid model.

So, the aim of this study is to analyze, numerically, the combined effect of thermal radiation and viscous dissipation on steady MHD flow and heat transfer of an upper-convected

In [11] a model for diffusion of a single phase fluid through a periodic partially- fissured medium was introduced; it was studied by two-scale convergence in [9], and in [40]

In particular, we show that the q-heat polynomials and the q-associated functions are closely related to the discrete q-Hermite I polynomials and the discrete q-Hermite II

Two numerical examples are described to demonstrate the application of the variational finite element analysis to simulate the hydraulic heads and free surface in a porous medium..

(A Weissenberg number is the ratio of the relaxation time of the fluid to a char- acteristic time associated with the flow.) Analytical solutions have been obtained for the
