【 摘 要 】

The main objective of this work is to study the performance of the boundary layer flow considering non-NewtonianWalter’s B fluid over the surface of an unstable cylinder to protect the surface of the cylinder from external heatingand cooling. The Soret and Dufour properties with heat and mass transmission have been encountered in the flowfield. Using the appropriate similarity transformations the leading PDE’s for the flow field have been altered into highordered non-linear coupled ODE’s. Series solutions of the subsequent problem are computed by using controllingprocedure homotopy analysis method. The properties of the included physical parameters in the problem, likeReynolds number, Walter’s B fluid parameter, Prandtl number, Schmidt numbers, Dufour and Soret numbers havebeen illustrated. The behavior of Skin friction, Sherwood number and local Nusselt number have been describednumerically for the dynamic constraints of the problem and the comparison of these physical parameters have beendisplayed with the experimental consequences in the existent literature. The optimal convergence of the appliedmethod has been patterned by plotting h-curves. Finally, the results, obtained from HAM, have been justified throughnumerical (ND-Solve) method and tabulated comparison.
