Abstract
The simulation of transport phenomena in porous media, such as the flow of fluids in petroleum reservoirs or the movement of contaminants in groundwater, requires solving complex partial differential equations (PDEs). These equations describe the interplay between spatial variations and temporal dynamics, often coupling variables like pressure, velocity, and concentration. Accurately resolving these interactions is critical for predicting system behavior and making informed engineering decisions. Numerical discretization methods are crucial in translating these continuous equations into solvable algebraic systems. Spatial discretization divides the domain into finite elements or cells, transforming spatial derivatives into algebraic expressions. This step is essential for capturing local variations in properties like permeability, porosity, or saturation. Temporal discretization, on the other hand, involves approximating time derivatives to evolve the solution through discrete time steps. Together, these techniques allow for the numerical solution of PDEs that govern transport in porous media.
