  • Abstract:
  • The influence of Diffusion – Thermo (Dufour) and Non-Darcian effect on Three - Component Rayleigh Benards (TCRB) convection in a two-layered system, has investigated analytically by using the Regular Perturbation technique. The upper and lower boundaries of the composite system are rigid and rigid-free with surface tension respectively, these boundaries are insulating to both heat and mass. At the interface of the composite system, the heat and heat flux, normal velocity, normal and shear stress, and mass and mass flux, are assumed to be continuous. The Non-Darcy term and Dufour term are employed in the momentum and energy equation respectively. The impact of various physical parameters on TCRB convection is investigated in a detailed manner and results are portrayed graphically.
