Efficient solution techniques for two-phase flow in heterogeneous porous media using exact Jacobians

Autor: Büsing, Henrik, Institute for Applied Geophysics and Geothermal Energy, E.ON Energy Research Center, RWTH Aachen University, Aachen, Germany

Publikováno v: Computational geosciences 25(1), 163-177 (2020). doi:10.1007/s10596-020-09995-w

Two efficient and scalable numerical solution methods will be compared using exact Jacobians to solve the fully coupled Newton systems arising during fully implicit discretization of the equations for two-phase flow in porous media. These methods use
