The existence of concentration gradient and temperature in the domain have mutual influence on propagation of heat and mass transfer. In this study, the mutual effect between concentration and temperature is coupled by presence of the Soret and Dufour parameter in concentration and energy equation respectively. A three-dimensional numerical analysis is presented for heat and mass transfer by varying solutal buoyancy force at fixed thermal buoyancy in the flow with induced forced convection by moving-lid and rotating cylinder. The heat and mass transfer (double diffusion flow) solver are framed in the open-source computational fluid dynamics tool OpenFOAM 5.0. The Reynolds number of Re = 1000 is kept same for both the sources (rotating cylinder and moving-lid). Thermal Rayleigh number of RaT = 10 6 and Richardson number of Ri = 1 are kept same for all the cases. The buoyancy ratio (thermal buoyancy to solutal buoyancy ratio) varies in the flow as N = 0.5, 1, 1.5. The configuration of forced convection varied by altering the angular rotational direction of cylinder (clockwise and counterclockwise) and the direction of moving-lid (positive and negative x-direction). The clockwise direction (CW) and positive x-direction of moving-lid velocity show the maximum mass transfer in terms of average Sherwood number ( Shavg) compared to other cases. The relevant quantities such as streamlines variation, isotherms, iso-concentration contours, Nuavg and Shavg are reported in detail.
