Statistical analysis of flow velocity field inside random packed beds

Abstract Immersed boundary method is used for simulation of fluid flow through random packed beds various particles (cylinders and rings) obtained in a separate numerical the packing process. Due to complexities structure velocity also highly complex despite laminar regime. The statistical characteristics field are examined detail compared between packings - not only probability distribution but novel measures that provide useful information about applicable simplified models similar structures. based on statistics deflection angle i.e. local vector inlet direction. proposed two-dimensional map allows assessment different values magnitude.
