FD-LBM Simulation of thermosolutal convection generated in an inclined enclosure in the presence of Soret and Dufour effects

An hybrid Lattice-Boltzman finite-difference method is proposed to assess the impact of the inclination angle of the cavity on thermosolutal natural convection of a binary fluid confined in a square cavity differentially heated and salted from two opposite walls with constant temperatures and concentrations. This method seems more flexible in implementing additional effects and apparently more efficient than the classical CFD methods. The study is conducted in the case of aiding buoyancy forces and many other controlling parameters. Results obtained showed important qualitative and quantitative effects of the governing parameters on fluid flow and heat and mass transfer characteristics. The heatlines and masslines concepts are also implemented to obtain additional details on heat and mass transfer processes.
