3D Lattice Boltzmann Code for Modeling Flow and Multi-Component Dispersion

摘要

This report documents the JB-PH lattice Boltzmann code, a program for modeling211u001emulti-component flow and dispersion. The lattice Boltzmann method is reviewed and 211u001emethods are compared for increasing the efficiency of the algorithms. Accuracy of 211u001ethe code is tested with four benchmark problems: (1) permeability of a simple 211u001ecubic array of spheres; (2) Taylor-Aris dispersion between infinite plates; (3) 211u001edispersion in a duct' and (4) dispersion in a simple cubic array of spheres. The 211u001ememory and speed requirements of the method are assessed in the context of the 211u001ebenchmarks. The code structure and purpose of each major function are described, 211u001eand instructions are given for compilation.
