Abstract
A numerical solution for the transient natural convection flow over a vertical cylinder under the combined buoyancy effect of heat and mass transfer is presented. The velocity, temperature and concentration pro files, local and average skin-friction, Nusselt number and Sherwood nu mber are shown graphically. It is observed that time taken to reach st eady state increases with Schmidt number and decreases as combined buo yancy ratio parameter N increases. Stability and convergence of the fi nite difference scheme are established.
