Molecular dynamics modelling of granular chute flow: density and velocity profiles

摘要: Abstract A molecular dynamics simulation technique is applied to the modelling of a granular chute flow, and density velocity profiles flows are examined by considering different inclination angles, rough smooth boundary conditions, accelerating fully developed flows. In general, non-linear, concave in shape there slip at base. However, linear profile with no can be obtained small angles therefore slow flow regime. For flows, show low zone near base, but base surface an stage for produce both resistance anti-rotational effects on flow.
