Supplemental Videos 4a and b show planar zigzag paths of short cylinders corresponding to Ar = 90 i.e. Re ≈ 250 (from Fernandes et al. 2005). The red line (Nx) indicates the horizontal projection of a unit vector parallel to the body symmetry axis. The black (Vz') and blue (Vx') lines display the evolution of the fluctuating velocity components along the vertical and horizontal directions respectively. For Supplemental Video 4a χ = 2. Positions of the body center of volume (left panel) are in mm; fluctuating velocities (right panel) are in mm s-1. Note that Nx and Vx' are almost in phase for χ = 2 whereas they are more than 90° out of phase for χ = 10.

Movie showing the depletion-layer pattern evolution as a response to a step input of 40 V. In particular we clearly see the complex process of wavelength selection by small vortices breaking up through fusion and transformation into still larger vortices until a quasi-steady like pattern is formed in the case of the deep (122-µm) microchamber.

In contrast to the case of the deep (122-µm) microchamber these patterns do not occur for the shallow (2-µm) microchamber. Instead a relatively uniform propagating concentration polarization layer front is observed.
