During confined flow of bulk solids in silos some characteristic
phenomena can be created, such as: sudden and significant increase of
wall stresses, different flow patterns, formation and propagation of
wall and interior shear zones, fluctuation of pressures and, strong
autogenous dynamic effects.
These phenomena have not been described or explained in detail yet. The
main intention of the experimental and theoretical research presented in
this book is to explain the above mentioned phenomena in granular bulk
solids and to describe them with numerical FE models verified by
experimental results.
