Abstract Grains are widely present in industrial productions and processing, and are stored in silos. In the silo, auxiliary
structures are added to achieve efficient production. However, little effort has been devoted to the influence of
the internal structure of the silo on the granular flow. In this work, a silo with a central decompression tube is
studied through experimental measurements and discrete element methods. Then, the influences of the central
decompression tube on the flow behavior of grains and wall pressure are analyzed. Results show that the grains are
in mass flow in the silo without a central decompression tube,… More >
