Query: DEM simulation of granular segregation in two-compartment system under
  zero gravity   In this paper, granular segregation in a two-compartment cell in zero gravity
is studied numerically by DEM simulation. In the simulation using a virtual
window method we find a non-monotonic flux, a function which governs the
segregation. A parameter is used to quantify the segregation. The effect of
three parameters: the total number of particles N, the excitation strength
{\Gamma}, and the position of the window coupling the two compartments, on the
segregation {\epsilon} and the waiting time {\tau} are investigated. It is
found that the segregation observed in zero gravity exists and does not depend
on the excitation strength {\Gamma}. The waiting time {\tau}, however, depends
strongly on {\Gamma}: Higher the {\Gamma}, lower the waiting time {\tau}. The
simulation results are important in guiding the SJ-10 satellite microgravity
experiments.
