Abstract
This report documents the JB_PH lattice Boltzmann code, a program for modeling multi-component flow and dispersion. The lattice Boltzmann method is reviewed and methods are compared for increasing the efficiency of the algorithms. Accuracy of the code is tested with four benchmark problems: (1) permeability of a simple cubic array of spheres; (2) Taylor-Aris dispersion between infinite plates; (3) dispersion in a duct; and (4) dispersion in a simple cubic array of spheres. The memory and speed requirements of the method are assessed in the context of the benchmarks. The code structure and purpose of each major function are described, and instructions are given for compilation.
