摘要：

Combined heat and mass transfer in natural convection along a vertical cylinder 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 in detail for both cases where the concentration gradients can either aid or oppose the thermal buoyancy forces. The effects of the curvature, the buoyancy parameter and the Lewis number on the temperature, concentration and flow fields, and on the surface heat and mass transfer rates are discussed. © 1990.
