摘要：

In this study, the effect of radiation on mixed convection along a vertical cylinder with uniform surface heat flux in a porous medium is investigated numerically using an implicit finite-difference method. Similar and nonsimilar solutions are obtained for combined radiation and mixed convection regime. Nusselt numbers are obtained for various values of different parameters. Several values of the power-law variation in surface heat flux, buoyancy, curvature, and mixed convection parameters are considered to study their effects on heat transfer rates. The Rosseland approximation is used to describe the radiative heat flux in energy equation.
