Lattice Boltzmann Simulations of Particle-scale flow

The lattice Boltzmann method (LBM) has emerged as a viable approach for computational fluid dynamics due to its high parallel performance and scalability. The LBM is well suited for simulations of complex and large-scale problems on supercomputers. Numerical investigations of resolved particle simulations can be performed by coupling the LBM with a discrete element method (DEM) for gas-solid flow containing large number of unary and binary (different size and density) particles. We are working on validation of LBM code (WalBerla) in collaboration with Prof. Ulrich Ruede, LSS FAU Erlangen, Germany. The validated LBM code will be further used to understand the dynamics of unary and binary gas-solid flows.
