Abstract
This analysis investigates the problem of heat transfer for steady flow in a two-dimensional Maxwell fluid between an axisymmetric channel having upper porous wall by incorporating thermal radiation impacts. An analytic solution is obtained for the resulting nonlinear equations using parameterized perturbation method (PPM). For studying the precision and strength of the present finding obtained by PPM, a comparison is presented along with the numerical findings (attained through shooting technique), and they were found to be in excellent agreement. The physical quantities of intersects are investigated including the Reynolds number, Nusselt number, power law index, radiation parameter and Prandtl number. It is observed from present investigation that the absolute value of skin friction coefficient is increased with an increase in Reynolds number. Also, it is evident from these results that magnitude of Nusselt number enhances by an increment in power law index, Prandtl number and Reynolds number. However, it has the reverse behavior for radiation parameter, as it decreases for higher values of radiation parameter.
