Abstract
Flow and transport in porous media have been subject in researches due to its wide range of applications like chemical, pharmaceutical and food as well as petroleum and groundwater engineering and in many other industrial applications. In this way, to improve the physical understand for such flows and the accuracy of existent models, the study of more realistic geometries would be necessary. In the current work, we present a strategy to generate a highly complex three-dimensional porous media. The porous media is generated by a controlled random function. Frequency points are controlled by a Fast Fourier Transform algorithm, allowing control the region with more pores or fractures. Afterward, a constructive solid geometry software is applied to create the domain. Pore-scale simulations have been conducted on porous media using OpenFOAM, for single and two-phase flow for Newtonian fluids. The accuracy and stability of the numerical method have been verified through the development of several test cases. The results showed the potential of the method to predict multiphase flow and the viability of the porous media generator to perform computational fluid dynamics simulations of different materials.
