By partitioning the simulation lattice into vertical slabs as shown in figure(4) it was possible to measure a concentration gradient vs. time. Figure(10) displays data for both Ar-Xe and Ar-Kr systems below their triple-point influenced by a temperature gradient of 1 K / lattice constant. The data shows that Ar diffuses to the region of lower temperature for both systems.
Figure 10:
Data displaying the concentration gradient developed for both Ar-Xe and Ar-Kr binary systems. Each slab number is assiciated with different sections of the lattice, for example Slab 5 is the center of the lattice).
