Abstract:
This paper considers numerical methods for approaching and simulate the Stokes–Darcy problem, with a
new boundary condition. We study herein a robust stabilized fully mixed discretization technique, this method
ensures the stability of the finite element scheme and does not use any Lagrange multipliers to introduce a
stabilization term in the temporal Stokes–Darcy problem discretization. The well-posedness of the finite
element scheme and its convergence analysis are also derived. Finally, the efficiency and accuracy of the
numerical methods are illustrated by different numerical tests
Key words:
Stokes–Darcy problem, mixed finite element method, free flow, porous media flow, stabilized scheme.
