This article considers the radiation effect on the flow of a Jeffery fluid with variable thermal conductivity. Similarity transformations are employed to convert the partial differential equations into ordinary differential equations. The resulting equations have been computed by the homotopy analysis method (HAM). The numerical values of the local Nusselt numbers are also computed. The comparison with the numerical solutions of θ′(0) is presented. The obtained results are displayed and physical aspects have been examined in detail.
Key words: Jeffery Fluid; Variable Thermal Conductivity; Non-Isothermal Stretching Surface; Porous Medium; Thermal Radiation.
