This work focuses on creating a recipe for parametrizing flow around assemblies of non-spherical particles. A multi-relaxation time lattice Boltzmann method (MRT-LBM) is used to simulate the flow. The research focuses on 3 different developments. First, different boundary conditions available in the literature for LBM are tested to identify the best for the flow problem. The second part of the thesis focuses on developing more widely applicable scaling laws for drag and lift of various isolated non-spherical particles. In the third part, a recipe to describe hydrodynamic forces on assemblies of axisymmetric, non-spherical particles is proposed. With the described parameters, drag, lift and torque correlations are proposed accordingly. This research is funded by the European Research Council under its consolidator grant scheme, contract no. 615096 (NonSphereFlow).
