Abstract
The DEM (Discrete Element Method) is one option for studying the kinematic behaviour of cylindrical pellets. The DEM experiments attempted to optimize the numerical model parameters that affected time and velocity as a cylindrical vessel emptied. This vessel was filled with cylindrical pellets. Optimization was accomplished by changing the coefficient of friction between particles and selecting the length accuracy grade of the sample cylindrical pellets. The initial state was a series of ten vessel-discharge experiments evaluated using PIV (Particle Image Velocimetry). The cylindrical pellet test samples were described according to their length in three accuracy grades. These cylindrical pellet length accuracy grades were subsequently used in the DEM simulations. The article discusses a comparison of the influence of the length accuracy grade of cylindrical pellets on optimal calibration of time and velocity when the cylindrical vessel is emptied. The accuracy grade of cylindrical pellet length in the DEM sample plays a significant role in relation to the complexity of a created simulation.

Summary
An increase in the demand for biomass is anticipated in the few years. The world needs enormous amounts of power to maintain current economic development. Energy from biomass is contributing to social and economic development as an alternative for future power demands [1]. Biomass possesses some adverse properties for storage and transportation, such as a heterogeneous composition of irregularly shaped particles or low-density particles. Pelletizing biomass results in improved storage and transportation properties [2]. Knowledge of biomass flow properties in this case has been significantly substantiated [3]. M.R. Wu [4] deals with the measurement and comparison of various forms of solid biomass. Issues in movement of these particles is based on the effect of friction parameters, particle shape and hopper geometry [5].
