Abstract

Lattice Boltzmann (LB) method is a novel approach for simulating fluid flow in complex systems. It has advantages including simplicity of extension to three dimensions and inherent treatment of complex phenomena. In this work the method is applied to simulate two-component fluid flow inside porous media. A novel technique to generate porous media has been developed using fractals. The two-component model correctly simulates different stages of the Rayleigh-Taylor (RT) instability, such as linear growth of the interface, developing of spikes and bubbles, and the Kelvin Helmholtz (KH) instability. The RT instability suffers from diffusion during the late stages of the simulation. The RT instability is simulated inside a porous medium where heavy and light fluids are displaced.
