Figure 8From: Analytic solutions of a simple advection-diffusion model of an oxygen transfer device Plots of the large x and z asymptotics of the analytic solution showing the travelling wave behaviour: (a) Plot of the numerically obtained contour \(c=(c^{*}+c_{0})/2\) (black) and the line \(z=z_{0}+x/\nu\) (red). (b) Travelling wave concentration profiles for values of \(x=5\) (black) to \(x=25\) (red) as a function of distance z.Back to article page
