Title: | Analysis of a linearization scheme for an interior penalty discontinuous Galerkin method for two phase flow in porous media with dynamic capillarity effects | Authors: | KARPINSKI, Stefan POP, Sorin Radu, Florin Adrian |
Issue Date: | 2017 | Source: | INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN ENGINEERING, 112(6), p. 553-577 | Abstract: | We present a linearization scheme for an interior penalty discontinuous Galerkin method for two phase porous media flow model which includes dynamic effects in the capillary pressure. The fluids are assumed immiscible and incompressible, and the solid matrix nondeformable. The physical laws are approximated in their original form, without using the global or complementary pressures. The linearization scheme does not require any regularization step. Furthermore, in contrast with Newton or Picard methods, there is no computation of derivatives involved. We prove rigorously that the scheme is robust and linearly convergent. We make an extensive parameter study to compare the behaviour of the L-scheme with the Newton method. | Notes: | Karpinski, S (reprint author), ESPRiT Engn GmbH, Munich, Germany. stefan.karpinski@esprit-engineering.de | Keywords: | two phase porous media flow; dynamic capillary pressure; interior penalty discontinuous Galerkin method; linearization method; convergence analysis; L-scheme | Document URI: | http://hdl.handle.net/1942/25329 | Link to publication/dataset: | http://onlinelibrary.wiley.com/doi/10.1002/nme.5526/full http://www.uhasselt.be/Documents/CMAT/Preprints/2016/preprint1605.pdf |
