dc.description.abstractAbstract: The Lattice Boltzmann Method (LBM) is an alternative to traditional Computational Fluid Dynamics (CFD). It has recently gained popularity due to its special capabilities, especially at scales where microscopic effects become important. The LBM originated in statistical mechanics, which implies the existence of particles contrasting with the continuum hypothesis assumed in CFD. Furthermore, LBM also contrasts with Molecular Dynamics (MD) and Monte Carlo (MC) simulations, since it does not focus on each individual particle but in their distribution, which allows for less computational demand in bigger domains. The meshes (or lattices) commonly used in LBM are simple, and the way the method is structured allows for code parallelization and versatility in simulating complex geometries, such as porous media. The present work focuses on the implementation and study of the LBM for simulating flows in porous media and under the effect of adsorption forces. These are areas of interest with great perspectives, especially for chemical engineering. A program was created and the code validated by performing simulations for cases that can be compared to analytical solutions (Poiseuille and Couette). More complex geometries (Poiseuille flow around an infinite cylinder, lid-driven cavity) were also used for evaluating the code, comparing the results to those available in the literature and CFD simulations. Flow in porous media was simulated in meshes generated using Monte Carlo simulations for the Ising model. The results were analyzed and compared to the Darcy's Law. Forces were also implemented and used to simulate body-forces and adsorption. Results were analyzed qualitatively and compared to other studies when possible. They proved to be very satisfactory for the simple geometries, and the flow behaved as expected in the complex ones. An alternative model for a distribution function was proposed to study binary flows of non-interacting particles, yielding good results when simulating adsorption. The results show the feasibility of using the LBM to simulate the studied systemsen
