Combined heat and mass transfer in non-Darcy natural convection flow along a permeable vertical cylinder embedded in a saturated porous medium is studied. The boundary layer analysis is formulated in terms of the combined thermal and solutal buoyancy effect. The flow field characteristics are analyzed using the implicit finite difference method as well as the local nonsimilarity method. The effect of the curvature, the buoyancy ratio, the Lewis number and the transpiration parameter on the local Nusselt number and the local Sherwood number are also studied. The results are presented in tabular form as well as graphically. Comparisons of the results obtained by the local nonsimilarity method are in excellent agreement with finite difference solution up to χ (the curvature parameter) of 10. The effects of different pertinent parameters on the velocity, temperature and species concentration profiles are also shown graphically.
