چکیده انگلیسی
The present analysis concentrates on the heat transfer analysis in the two-dimension viscoelastic fluid flow over an exponential stretching sheet. The medium is taken to be porous in the presence of Newtonian heating. Cattaneo-Christov heat flux model is utilized instead of Fourier's law of heat conduction in the evaluation of heat flux. The transport equations for the flow problem are reduced into nonlinear ordinary differential equations using exponential type similarity transformation. The analytical series solutions are obtained for the boundary value problem by using Optimal HAM. The impacts of different parameters counting the viscoelastic parameter, porosity parameter, Conjugate parameter, Prandtl number and relaxation time parameter are analyzed through graphs. It is observed that the thermal relaxation parameter results in the reduction of temperature field, and an increase in the viscoelastic parameter results in the enhancement of axial velocity.
