Discrete Element Method in the Design of Transport Systems

Introduces and explains fully the Discrete Element Method using measured values as inputs for the Method Shows whether calculated simulations and real measured values models can be used for design Illustrates how to validate, calibrate, and optimize the dynamic processes of bulk elevators Explains how to test transport and storage equipment before it is produced using dynamic simulation of material flow on transport lines, saving time and money

Ing. Daniel Gelnar Ph.D. received his doctoral degree in 2016 from Vysoká kola báská, The Technical University of Ostrava, in the Czech Republic. His research concerns deals with the design and optimization of the bucket elevator using the discrete element method (DEM).

Prof. Ing. Jií Zegzulka CSc. received his Ph.D. in 1993 from Vysoká kola báská, The Technical University of Ostrava in the Czech Republic, Faculty of Mechanical Engineering, Field - Design and Process Engineering. In 2004 he became full professor and, in 2010, joined the ENET Centre (Energy Units for Utilization of non-Traditional Energy Sources) as senior researcher. The research in his group is focused on development of transport equipment for bulk materials, measuring of physical and mechanical properties of powders and DEM modelling. He is member of European Federation of Chemical Engineering (EFCE), Mechanics of Particulate Solids and Czech Science Foundation.
