Plots of the mean velocity fields and corresponding streamlines discussed in Section 3.2: (a) v^bead; (b) v^L; (c) v^M. The color map represents the velocity magnitudes, whereas the lines depict streamlines. In all cases, the channel dimensions (cf. Fig. 3) are L = 300 μm, H = 600 μm, α = 15° , and h = 200 μm. The wall displacement was only in the y direction with magnitude 1 μm.
