Numerical study of double diffusive convection in a cylindrical annular geometry Validation and mesh sensibility
In this paper, we consider the problem of double diffusion in an annular cylindrical space with an aspect ratio R=2. The ADI method has been used to describe the two-dimensional symmetric solutions in terms of isotherms, streamlines and iso-concentrations. This numerical study has been validated both by comparing the results to the pure thermal case and by analyzing the case of weak solutal buoyancies. The influence of the mesh on the numerical results was also studied. The influence of thermal and solutal buoyancies was investigated.
Keywords: Natural convection, Double diffusion, Finite difference, Buoyancy ratio.
