Abstract
In the present work, we generate a small section of a randomly packed bed consisting of spherical particles with rigid particle dynamics simulations. We perform particle-resolved simulations of turbulent flow. The DNS are based on the LBM and performed with the software framework waLBerla. The RANS simulations and LES are based on the FVM and performed using the CFD toolbox OpenFOAM. Our results help us to evaluate the accuracy of different turbulence models to predict velocity and pressure distributions in packed beds. These insights allow us to use CFD simulations with turbulence models reliably to analyze transport limitations and the reaction performance of packed bed reactors.
