Global BV solutions for a model of multi-species mixture in porous media
— We consider an initial boundary value problemfor a nonlinear differential system consisting of one équation ofparabolic type coupled with a nxn semi-linear hyperbolic system offirst order. This system of équations describes a model of compressible miscible displacement ofn+1 chemical species in porous media, in the absence of diffusion and dispersion. In one-dimensional spacet we construct a ...
متن کاملA Mixture Model for Foamy Oil Flow in Porous Media
The processes of nucleation, bubble growth and finally the creation of connected gas during the pressure draw-down in an oil reservoir are discussed. From these mechanisms, possible descriptions of foamy oil production appear. One of these mechanisms is the creation of bubbles, small compared to pore sizes, which move with the oil phase and which push the oil out of the reservoir. If this mecha...
متن کاملA New Approach for Constructing Pore Network Model of Two Phase Flow in Porous Media
Development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. In this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. Af...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Global Existence of Large BV Solutions in a Model of Granular Flow
In this paper we analyze a set of equations proposed by Hadeler and Kuttler [20], describing the flow of granular matter in terms of the heights of a standing layer and of a moving layer. By a suitable change of variables, the system can be written as a 2 × 2 hyperbolic system of balance laws, which we study in the one-dimensional case. The system is linearly degenerate along two straight lines...
