A robust iterative scheme for the slightly compressible Darcy-Forchheimer equations

Laura Portero, Andrés Arrarás, Francisco J. Gaspar +1

We study the slightly compressible Darcy-Forchheimer equations modeling gas flow in porous media, particularly in applications related to combustion processes. The equations are di…
