The effect of changes of on (a) the oxygen concentration and (b) pH value (mMol/lit) at the end of simulation after subtracting each lattice from the lattice with . (c) The number of cells in each layer of the lattice in Figure 12(a) at the end of simulation. Three layers with different oxygen concentrations are considered. Ox1: , Ox2: relative oxygen concentration is between and , and Ox2: .
