electrodes were patterned on the floor of the mixing channel. The electrodes are 2 mm long and 75 m

apart. Phenol and water are the working fluids for this system. The water-phenol-water system was
realized by the three inlets. AC voltages with a root-mean-square values from 0 to 45 V and
frequencies ranging from 250 kHz to 10 MHz were used for disturbing the interfaces between phenol
and water.
Tsouris et al. [31] used a different electrode configuration to disturb the interface between the two
streams, Fig. 7.15 (c). The electric field is parallel to the flow direction. The mixing fluids are butanol.
