On Modeling Flow of a Large Deforming Porous Medium with Rate-Dependent Coulomb Friction Conditions
Original language description
The paper introduces development of a computational model describing oil expression from oil-containing seeds. The principles of compression in the rotating screw pressing machine are based on interplay between the screw rotor geometry, the related kinematics and the friction forces acting on the surfaces of the rotor and stator of the machine. We consider a poroelastic biphasic material of the Biot type. Within one time increment step, the physical elds involved in the problem are analyzed using the Lagrangian conguration; in order to compute the next time-increment, this con- guration is updated using the upwind numerical scheme. Such a treatment requires a projection of the data between two non-matching FE meshes. On the rotor/stator surfaces the compressed material is subjected to the Coulomb friction conditions, which make each incremental subproblem strongly non-linear. For numerical solution of this problem we employ frictional multipliers and we use the semi-smooth Newton metho
