Application of the Lattice Boltzmann CFD Method on HPC Systems to Analyse the Flow in Fixed-Bed Reactors

The increasing computational power and new numerical methods give the possibility for more detailed investigations of complex physical phenomena which are typical in science and engineering. In the first part of this paper, we show how CFD simulations of the flows through packed beds using the lattice Boltzmann approach can be used to get local and detailed information about the physical transport processes. The second part deals with the performance of the lattice Boltzmann method on different hardware platforms. It shows that this modern numerical method also needs adequate computers, i.e. high performance computers, to give best performance.
