Figure 3.4

Two-dimensional contact with solute transport. The semi-cylindrical slab has a radius of 3 mm and an initial solute concentration of 0 mM (t = 0). The bottom rectangular slab dimensions are 3 mm × 2 mm and the initial solute concentration is 1 mM. The top slab is displaced downward by 2 mm in 1 s, then allowed to relax. Solute transports from the bottom slab to the top slab, while also diffusing out into the ambient bath. In the early time response (t = 1 s), solute transport occurs over a thin boundary layer across the contact interface. Over time, the solute concentration decreases in both slabs, eventually reducing to zero. Contour plots demonstrate continuity of the (effective) concentration across the contact interface.
