Abstract
New numerical methods such as the lattice Boltzmann approach together with the increasing computational power can provide a detailed insight into the flow and transport processes in complex three dimensional geometries. The present paper demonstrates this approach by investigating inhomogeneities in the 3-D flow field of reacting species in a tubular fixed bed reactor of small tube-toparticle diameter ratio. For such reactors detailed 3-D simulations are of technical and economical interest as conventional modelling methods cannot correctly predict the local flow behaviour. However, these local inhomogeneities can significantly influence the reactor performance. Beside the discussion of the reaction engineering results, also the computational performance of the applied method is described.
