Resumen en español

Heat and mass transfer flow along a vertical plate under the combined buoyancy force of thermal and species diffusion in the presence of a transverse magnetic field is investigated. The boundary layer equations are transformed in to ordinary differential equations with similarity transformations. The effects of variable viscosity and thermal conductivity on velocity profile, temperature profile and concentration profiles are investigated by solving the governing transformed ordinary differential equations with the help of Runge-Kutta shooting method and plotted graphically.
