Keywords: Peristalsis; Jeffrey fluid; eat transfer. _ INTRODUCTION Peristaltic motion in a cannel/tube is now known as an important type of flow occurring in several engineering and pysiological processes. Te peristalsis is well known to te pysiologists to be one of te major mecanisms of fluid transport in a biological system and appears in urine transport from kidney to bladder troug te ureter, movement of cyme in te gastrointestinal tract, te movement of spermatozoa in te ductus effeerentes of te male reproductive tract and te ovum in te female fallopian tube, te transport of lymp in te lympatic vessels and vasomotion of small blood vessels suc as arterioles, venules and capillaries. Suc mecanism as several applications in engineering and in biomedical systems including roller and finger pumps. Te need for peristaltic pumping may arise in circumstances were it is desirable to avoid using any internal moving part suc as pistons in pumping process. fter te experimental work of Latam [] on peristaltic transport, Sapiro et al. [] made a detailed investigation of peristaltic pumping of a Newtonian fluid in a flexible cannel and a circular tube. Sud et al. [3] analyzed 439
2 te pumping action of blood flow in te presence of a magnetic field. Even toug it is observed in living systems for many centuries, te matematical modeling of peristaltic transport began wit trend setting works by Sapiro et al.[4] using wave frame of reference and Fung and Yin[5] using laboratory frame of reference. Hayat et al. [6] studied te peristaltic flow of a micropolar fluid in a cannel wit different wave frames. Hayat and li [7] investigated te peristaltic motion of a Jeffrey fluid under te effect of a magnetic field. Vajravelu et al. [8] studied te peristaltic transport of a Casson fluid in contact wit a Newtonian fluid in a circular tube wit permeable wall. In pysiological peristalsis, te pumping fluid may be considered as a Newtonian or a non- Newtonian fluid. Kapur [9] made teoretical investigations of blood flows by considering blood as a Newtonian as well as non- Newtonian fluids. Radakrisnamacarya and Srinivasulu [] studied te influence of wall properties on peristaltic transport wit eat transfer. Mekeimer and bd Elmaboud [] analyzed te influence of eat transfer and magnetic field on peristaltic transport of Newtonian fluid in a vertical annulus. Hayat et al. [] studied te effect of eat transfer on te peristaltic flow of an electrically conducting fluid in a porous space. Krisna Kumari et.al[3] studied te peristaltic pumping of a magnetoydrodynamic casson fluid in an inclined cannel. Ravi Kumar et.al[4] considered power-law fluid in te study of peristaltic transport. In tis paper, peristaltic flow of a conducting Jeffrey fluid in a vertical porous cannel wit eat transfer is studied. Using te perturbation tecnique, te nonlinear governing equations are solved. Te expressions for velocity, temperature and te pressure rise per one wave lengt are determined. Te effects of different parameters on te temperature and te pumping caracteristics are discussed troug graps. MTHEMTICL FORMULTION We consider te motion of a MHD Jeffrey fluid in a two-dimensional vertical porous cannel induced by sinusoidal waves propagating wit constant speed c along te cannel walls. For simplicity, we restrict our discussion to te alf widt of te cannel. We assume tat a uniform magnetic field strengt B is applied as sown in Figure. and te induced magnetic field is assumed to be negligible. Te wall deformations are given by π Y = H ( x, t) = a + b cos ( x ct) (rigt wall) λ () π Y = H ( x, t) = a b cos ( x ct) (left wall) λ () were a is te widt of te cannel, b is amplitude of te waves and λ is te wave lengt. Te constitutive equations for an incompressible Jeffrey fluid are T = p I + s (3) 44
3 ... µ s = γ + λγ (4) + λ were T and s are Caucy stress tensor and extra stress tensor respectively, p is te pressure, I is te identity tensor, λ is te ratio of relaxation to retardation times λ is te retardation time,. γ is sear rate and dots over te quantities indicate differentiation wit respect to time. Figure. Pysical model In laboratory frame, te continuity equation is U V + = X Y Te equations of motion are U U P S XX S XY µ ρ U + V = + + U + ρ gα( T T ) X Y X X Y k U U P S XY S YY µ ρ U V + = + + V X Y X X Y k (5) (6) (7) 44
4 Te equation of energy is T T T T U V V U µ ρ cp U + V = k ( + ) + µ µ U X Y X Y X Y X Y k Te boundary conditions on velocity and temperature fields are U = and T = T at Y = H X ( ) U T = and = at Y = Y Y (9) (8) were U, V are te velocity components in te laboratory frame ( X, Y ), ρ is density, µ is te coefficient of viscosity of te fluid, c p is te specific eat at constant pressure, α is te coefficient of linear termal expansion of te fluid, k is te termal conductivity, k is permeability and T is temperature of te fluid. We sall carry out tis investigation in a coordinate system moving wit te wave speed c, in wic te boundary sape is stationary. Te coordinates and velocities in te laboratory frame ( X, Y ) and te wave frame ( x, y) are related by x = X ct, y = Y, u = U c, v = V, p = P( x, t) were u, v are te velocity components and p, P are te pressures in wave and fixed frames. Equations (5)-(9) can be reduced into wave frame as follows u v + = x y u u p S xx S xy µ ρ ( u + c) + v = + + ( u + c) + ρ gα ( T T ) x y x x y k v v p S xy S yy µ ρ ( u c) v + + = + + v x y y x y k T T T T u v v u µ ρ cp u + c + v = k + + µ µ u c x x y x x k ( ) ( ) Boundary conditions in wave frame are u + c = and T = T at y = H ( x) u T = and = at y = y y () () () (3) (4) we introduce te following non dimensional quantities : 44

Te basic equations ()-(3) can be expressed in te non-dimensional form as follows u v + = x u u p S ( ) xx S xy δ R u v δ + + ( σ M )( u ) Gθ x y = x x 3 v v p Sxy S yy δ R ( u + ) + v δ δ δ ( σ M ) v x y = x x θ θ θ θ u v δ Pr R ( u + ) + v δ δ N x y = x x v u N δ N σ M u ( ) ( + ) + x were δ δλc v u Sxx = + u + + λ a x δ x δλc v u v Sxy = + u + + δ + λ a x δ x δ δλc v u S yy = + u + + λ a x δ nd (6) (7) (8) (9) sxy u = y + λ δ Te non-dimensional boundary conditions are u = and θ = at y = 443

Due to teir nonlinearity tey are difficult to solve. However te fact N is small in most practical problems allows us to employ a perturbation tecnique to solve tese non-linear equations. We write u = u + Nu θ = θ + Nθ (5) Using te above relations, te equations (), (3) and (4) become d( p + Np ) ( u + Nu ) = + ( σ + M )( u + Nu + ) + G( θ + Nθ ) dx + λ (6) 444
