Investigation on the discharge process in a flat-bottomed bin: the experimental measurements and theoretical predictions

Abstract

This paper presents comparison between experimental measurements of wall pressures made in the flat bottomed silo model and theoretical calculations. The numerical and simplified analytical analysis of deformation and stress states in a silo model during discharge was considered. In the analytical solution, we discuss a method for solving a set of differential equations governing the flow in the model, while numerical analysis is considered by implementing the relations based on discrete element method. The experiments were performed in a bin model made of plexi and filled with the pea grains, while the adequacy of the theoretical and measured values was considered.
