Lattice Boltzmann Simulation of Diffusion-Convection Systems with Surface Chemical Reaction

Chemical reactions on solid surfaces are ubiquitous in natural and industrial processes. In many situations, the reaction is complicated by diffusion and convection of reactants in the surrounding media. The system as a whole is usually highly nonlinear. Theoretical analysis for this complicated phenomenon is difficult if not entirely impossible. It is highly desired to develop efficient computational tools to simulate this process. The lattice Boltzmann method, based on mesoscopic description of fluid systems, is quite suitable for this purpose. This study will present a lattice Boltzmann scheme for simulating the diffusion-convection systems with surface chemical reactions.
