Fig. 12.

Volume fractions of Veillonella at different times corresponding to different initial distribution with various corrlation lengths. Figure from left to right refer to simulation results corresponding to different initial correlation lengths of $2\Delta x$, $4\Delta x$ and $8\Delta x$. Figure from top to bottom refer to simulation results at different times of $t=\text{0.1 day}$ ($T=0.1$), $t=\text{0.5 day}$ ($T=0.5$) and $t=\text{1.5 day}$ ($T=1.5$)
