On the use of the consistent splitting scheme for double-diffusive convection flows in mixed finite element formulations.

This paper describes the so-called consistent splitting scheme (CSS) for solving unsteady double-diffusive convection (DDC) problems using the mixed finite element method. The CSS was chosen to numerically solve the primitive form of the unsteady governing equations for decoupling the velocity variables and the pressure. Both first- and second-order accurate temporal and spatial approximations have been implemented for unsteady DDC problems. The results obtained with the described numerical methods compare favourably with the existing numerical result. [ABSTRACT FROM AUTHOR]
