We introduce a new multiscale finite volume framework for the simulation of multi-phase flow in heterogenous and anisotropic porous media on quite general unstructured grids that enable geophysical grid defined properties to be used directly on a hig

The focus of this work is to investigate and to apply, for the first time, a very high-resolution correction procedure via reconstruction (CPR) numerical discretization technique for the hyperbolic saturation equation that describes 1-D oil-water dis

In this paper, we present a new linear cell-centered finite volume multipoint flux approximation (MPFA-QL) scheme for discretizing diffusion problems on general polygonal meshes. This scheme uses a quasi-local stencil, based upon the conormal decompo

To assess the structural integrity of pipelines with corrosion defects for transportation of petroleum, several methods can be applied. The Semi-Empirical Analytical Methods, although usually providing very conservative results, which results in prem

The study of heat transfer within the human eye is of utmost importance due to the wide variety of existing treatments commonly given by the aid of devices which expose the eye to external heat sources. Also, the ocular tissues are very sensitive to

Summary In this paper, we propose a full-cell-centered finite-volume approach to simulate two-phase flow in heterogeneous and anisotropic petroleum reservoirs. We adopt a segregated formulation where the pressure equation is discretized by a multipoi
