The current study is concerned with the investigation of the combined effects of thermophoretic motion and thermal radiation on steady, viscous, incompressible and two-dimensional mixed convection flow of optically dense grey fluid. The governing equations are made dimensionless by using suitable dimensionless variables and further are transformed into a convenient form for a numerical algorithm. The transformed flow model is integrated by using an efficient finite difference methd. Effects of the assorted parameters involved in the flow model such as Prandtl number, mixed convection parameter, modified mixed convection parameter, Schmidt number, radiation parameter, thermophoresis parameter and thermophoretic coefficient on velocity field, temperature distribution, and mass concentration are demonstrated graphically. The numerical results of skin friction, the heat transfer rate and the mass transfer rate under the effect of pertinent parameters are displayed in tabular form.
