Double-diffusive fingering convection in a porous medium (Q1207079)

We consider nonlinear two-dimensional, horizontally periodic, double- diffusive fingering convection in a saturated porous medium. The Darcy equation, including Brinkman and Forchheimer terms to account for viscous and inertia effects, respectively, is used for the momentum equation. A mixed Galerkin-finite difference method (Galerkin in the horizontal direction, finite difference in the vertical direction) is developed to solve the initial-boundary value problem.
