Mixed convection flow of an optically dense viscous incompressible fluid
along a vertical cylinder including the effects of radiation has been studied
when the surface temperature is kept uniform. With appropriate transformations,
the boundary layer equations governing the flow are reduced to local
non-similarity equations. Solutions to the governing equations are obtained by
employing an implicit finite difference method together with the Keller box
scheme, as well the local non-similar method with a second order trunction, for
values of the transverse curvature parameter, x, in the range [0,10]. Effects of
the pertinant parameters, such as the radiation parameter, Rd, the surface
temperature parameter, qw, and the buoyancy parameter W , taking Prandtl number,
Pr, equal to 0.7, on the local skin-friction and the local Nusselt are explored
in this stidy.
