Résumé

A numerical study of mixed convection heat and mass transfer along a vertical wavy surface was carried out numerically. The wavy surface was maintained at uniform wall temperature and constant wall concentration that is higher than that of the ambient. A simple coordinate transformation was employed to transform the complex wavy surface to a flat plate. A marching finite-difference scheme was used for the analysis. The buoyancy ratio N, amplitude-wavelength ratio, and Richardson number (Gr/Re2) are important parameters for this problem. The numerical results, including the developments of skin-friction coefficient, velocity, temperature, concentration, Nusselt number as well as Sherwood number along the wavy surface were presented. The effects of the buoyancy ratio N and the dimensionless amplitude of wavy surface on the local Nusselt number and the local Sherwood number were examined in detail.
