Effect of rate of monomer supply: (Left) Location of gel front x_g(t) vs. time, (middle) total gel mass ${\int }_{-L}^L{\theta }_g(x,t)dx$ vs. total mass ${\int }_{-L}^L({\theta }_g(x,t)+{\theta }_s(x,t))dx$, and (right), final gel mass distribution (at t = 10) vs. x for simulations with D = D₁ = 0.02 and source term Eq. (46) with S_m = 2 and various values of λ (solid curves), or spatially-uniform source term (dashed lines). $\lambda =\frac{16}{3}$ (blue), $\lambda =\frac{4}{3}$ (red), $\lambda =\frac{1}{3}$ (green), $\lambda =\frac{1}{12}$ (black). Final gel mass distribution vs. x (right) for an initial monomer supply Eq. (45) with S_i = 2 (magenta) or for a spatially-uniform source with the same total amount of monomer (dashed black).
