MAHDY, A.; MOHAMED, R.A.  e  HADY, F.M.. Heat and mass transfer in MHD free convection along a vertical wavy plate with variable surface heat and mass flux. Lat. Am. appl. res. [online]. 2009, vol.39, n.4, pp.337-344. ISSN 0327-0793.

The problem of combined heat and mass transfer in buoyancy-induced MHD natural convection flow of an electrically conducting fluid along a vertical wavy plate with power-law variation of both heat and mass flux was investigated. The resulting transformed governing equations are solved numerically by an implicit finite-difference scheme. The results are presented for the major parameters including the wave amplitude a, the magnetic parameter Mn, the buoyancy ratio between species and thermal diffusion Br, the Lewis number Le, and the power-law parameter ?. A systematic study on the effects of the various parameters on flow, heat and mass transfer characteristics is carried out.
