Numerical study of double-diffusive free convection from a vertical surface

The double-diffusive free convective flow from a vertical surface has been studied numerically. The mass, momentum, energy and species conservation equations have been solved by a inite-difference method using an explicit scheme. Boundary layer and Boussinesq approximations have been incorporated. The velocity, temperature and concentration profiles indicate complex interaction between temperature and concentration driven buoyancy flows. The effects of Schmidt number and buoyancy ratio on the temperature profile have been discussed. The role of temperature stratification in the ambient has been highlighted
