In this work, granular segregation in a two-compartment cell (Maxwell’s Demon) under zero gravity is studied numerically by DEM simulation for comparison with the experimental observation in satellite SJ-10. The effect of three parameters: the total number of particlesN, the excitation strengthΓ, and the position of the window coupling the two compartments, on the segregationε and the waiting timeτ are investigated. In the simulation, non-zero segregation under zero gravity is obtained, and the segregation ε is found independent of the excitation strengthΓ. The waiting time τ, however, depends strongly onΓ.
For higher acceleration Γ, |εi| reaches steady state valueε faster.
