Lattice Boltzmann simulation and its concurrent visualization on the SX-6 supercomputer

An emerging numerical method for simulating reactive flows in complex geometries, called the lattice Boltzmann method, is presented in combination with a concurrent visualization system. This combination enables an efficient simulation and visualization of time dependent transport and reaction processes such as the pollutant transport in porous media and the chemical processes in fixed bed reactors. The sustained computational performance of this lattice Boltzmann code on the NEC SX-6 supercomputer is 73% with respect to the theoretical maximum performance of its vector processors. An extension to the standard lattice Boltzmann model for adsorption processes is given together with simulation results and visualization examples for adsorption in porous media.
