The comparison of cluster distribution for PBC and fixed boundary condition. The simulation parameters are μpp = μpw = 0.1, ε = 0.9, and Lx = 70 mm, N = 5000. The slice shown in the figure is chosen in the middle of the cell, Lx = 30 mm–40 mm. The chromaticity diagram shows ϕlocal from 0.05 to 0.65.
