Computational domain discretization is the pre-processing stage in CFD analysis and it highly contributes to the solution error as well as the numerical stability of a model. The discretization of domain representing a packed bed of granular material is a demanding task due to the topology of the model consisting of spherical granules contacting tangentially. Therefore the aim of the research is to define guidelines to effectively discretize the computational domain representing the packed bed of granular material, validate it using Particle Image Velocimetry (PIV) and evaluate the impact of variable inflow velocity on the experimental and numerical research results.
