摘要

Beverloo’s scaling law is capable to describe the flow rate of grains discharging from hoppers.In this paper it shows the Beverloo’s scaling law is valid for varying material parameters.Then the flow rates from a hopper with different hopper and orifice size(D,D0)are studied by running large-scale simulations.When hopper size is fixed,numerical results show that Beverloo’s law is valid even if the orifice diameter is very large and then the criteria for this law are discussed.
