  • Abstract:
  • The non-darcy model was used to do analytical study on triple diffusive Marangoni (TDM) convection with Diffusion-thermo effects in a two-layered system. The lower border of the porous layer is rigid, but the top boundary of the fluid layer is free, with surface tension fluctuating with temperature and concentration. Both barriers provide thermal and mass insulation. The normal velocity, normal tension, shear stress, mass, mass flow, and heat are all assumed to be continuous at the contact. A detailed analysis of the impact of numerous physical conditions on TDM convection is carried out, with the results visibly exhibited. It has been explored how the Dufour parameter influences TDM convection in a two-layer system when the energy flux generated by the mass gradient develops. The software MATHEMATICA is used to plot the graphs
