A robust linearization scheme for finite volume based discretizations for simulation of two-phase flow in porous media

Abstract: a b s t r a c tIn this work we consider a mathematical model for two-phase flow in porous media. The fluids are assumed immiscible and incompressible and the solid matrix non-deformable. The mathematical model for the two-phase flow is written in terms of the global pressure and a complementary pressure (obtained by using the Kirchhoff transformation) as primary unknowns. For the spatial discretization, finite volumes have been used (more precisely the multi-point flux approximation method) and in time the bac… Show more

“…An efficient combination of the modified Picard and the Newton method, the Picard/Newton method is proposed in [20]. For the sake of completeness we mention also the accelerated Picard method [21] for Richards' equation and the semi-smooth Newton method [19] and L−method [30] for two-phase flow in porous media, as valuable linearization methods.…”

“…(a) FOU (b) FVBJ We note that [14] employed a similar linearisation with constant derivative in the iteration applied to a global pressure formulation and convergence of the iterative process was shown. We now consider a variety of tests on structured and unstructured grids.…”

“…For solving the nonlinear problem, we propose an iteration scheme that builds on the ideas in (the ‘L’‐scheme). The idea is to construct a sequence of triplets false(swn+1,i,pnn+1,i,pcn+1,ifalse) converging as i to the solution false(swn+1,pnn+1,pcn+1false) of Problem .…”

“…The previous texts has motivated the linearization schemes proposed in for the finite element, finite volume and the mixed finite element discretization of porous media flow models. The idea of the linearization scheme is to add an additional term in the form of L·(Solution_Current_IterationSolution_Old_Iteration), with L being a parameter that has to be chosen sufficiently large.…”
