Contour plots of C obtained using values of γ = 0 and Pec = 0.015 (a), γ = 3 × 103 and Pec = 0.015 (b), γ = 0 and Pec = 0.08 (c), and γ = 3 × 103 and Pec = 0.08 (d), all with fixed δ = 0.001. Within each subfigure, the upper plot is an enlargement of the region in the dotted box marked on the lower plot. Note that a spatially homogeneous transmural water flux (with the same average velocity as the heterogeneous flux used here) would result in a constant nondimensional concentration of unity adjacent to the endothelium.
