SIMULATION OF SILO DISCHARGE IN PARTICLE FLOW CODE AND RESEARCH OF SOLIDS PRESSURE ON SILO WALL

摘要

Under the circumstances of eccentric discharge, the silo wall could be buckled. In the Chinese Code of grain steel silo design, only the static pressure of solids on silo wall is given. In this paper, the particle flow code PFC2D and PFC30 are used to research the pressure distribution during discharge, especially eccentric discharge by the parameter analysis method. Finally, combined the results of particle flow code and the several assumptions, one probable pressure distribution on silo wall during eccentric discharge is given.
