From: Electrokinetic instability in microchannel ferrofluid/water co-flows
Channel depth effect on the electrokinetic instability of the ferrofluid (0.2× EMG 408) and water co-flow at the threshold electric field: (a) experimental images (dark for ferrofluid and white for water); (b) numerical predictions of ferrofluid concentration field (red for ferrofluid and blue for water) from the depth-averaged model. All images are each obtained at 20 s after the corresponding experimental or numerical threshold electric field (labeled on the image) is applied.
