2 AAM: Intern. J., Vol. 2, Issue 2 (December Introduction Peristaltic transport is an important mechanism used to describe a progressive wave of contraction along the tube whose cross sectional area consequently varies. Peristalsis is an inherent property of many tubular organs of the human body. The peristaltic transport is also exploited for industrial applications like transport of corrosive and noxious fluids, blood pumps in heart lung machine, sanitary fluid transport. In view of its importance, the study of peristaltic transport of Newtonian and non-newtonian fluids under different conditions have been investigated by several authors [Latham (966, Fung and Yih (968, Shapiro et al. (969, Devi & Devanathan (975, Meijing et al. (993, Prasad & Radhakrishnamacharya (2009, Pincombe et al. (999, Prasad et. al. (205, Santhosh et al. (205]. It is realized that the materials of nanometer dimensions have shown remarkable physical and chemical properties which paved the way for the immense contribution of Nanotechnology in the industry. Ethylene glycol, oil and water are the general base fluids used for the nanofluid phenomenon. The wider applications of nano fluids in heat transfer are Microelectronics, fuel cells, pharmaceutical processes, hybrid-powered engines, domestic refrigerator, chiller, nuclear reactor coolant, grinding and space technology, etc. They explore increased thermal conductivity, counterbalancing the convective heat transfer coefficient to the base fluid. Several researchers attention has been drawn by the wide-ranging thermal properties of nano fluids for new production of heat transfer fluids in automotive cooling significations, heat exchangers, and implants. Extensive literature is available on the study of nanofluid and its applications. Choi (995 was the pioneer of study of nano fluid technology. Peristaltic flow of nano fluid in a non-uniform tube was studied by Akbar (202. Mathematical model for the peristaltic flow of nano fluid through eccentric tubes comprising porous medium was investigated by Nadeem et al. (204. Nadeem et al. (204 studied effects of heat and mass transfer on peristaltic flow of a nano fluid between eccentric cylinders. Study of peristaltic transport of nanoparticles of micropolar fluid with heat and mass transfer effect in an inclined tube was investigated by Prasad et al. (205. Maruthi Prasad et al. (205 also studied Peristaltic transport of a nano fluid in an inclined tube. It is well known that in many physiological flows, the nature of the fluid at the core region of the tube is different compared to that near the wall. So several researches have done work on the effect of peripheral layer on peristaltic flow of fluids with particular reference to physiological systems. Effects of peripheral layer on peristaltic transport of a bio-fluid was studied by Shukla et al. (980. Srivastava and Srivastava (982 investigated peristaltic transport of a two-layered model of physiological fluid. Brasseur et al. (987 studied the influence of a peripheral layer of different viscosity on peristaltic pumping with Newtonian fluids. Rao and Usha (995 studied
3 970 N. Subadra et al. peristaltic transport of two immiscible viscous fluids in a circular tube. Prasad & Radhakrishnamacharya (2009 investigated the effect of peripheral layer on peristaltic transport of a couple-stress fluid. Effect of peripheral layer on peristaltic transport of a micropolar fluid was studied by Prasad and Radhakrishnamacharya (2009. However, the study of effect of peripheral layer on peristaltic transport of a nano fluid was not studied. Motivated by these studies, the study of effect of peripheral layer on peristaltic transport of a nano fluid, under the assumption of long wavelength and low Reynolds number has been done. To solve the resulting equations of the temperature profile and nanoparticle phenomena, Homotopy perturbation method has been used. The analytical solutions of velocity, pressure drop, frictional force and effect of heat and mass transfer are obtained. The effects of various parameters on these flow variables are investigated and graphically displayed. 2. Mathematical Formulation Consider the peristaltic transport of a nano fluid which is surrounded by Newtonian fluid in an axisymmetric tube of radius a, with core radius a. Choosing the polar coordinate system (R, θ, Z, the wall deformation due to propagation of an infinite train of peristaltic waves is given by R = H(Z, t = a + b sin 2π λ (Z ct, ( where, b is the amplitude, λ is the wave length, c is the speed of the wave. Following Prasad et al. (2009 the geometry of the interface between the peripheral layer and core region is R = H (Z, t = a + b sin 2π λ (Z ct, (2 where, a is the mean radius and b is the amplitude of the central layer. We use the transformation z = Z ct, r = R, θ = θ, w = W c, u = U.
