“…Most literature on EW is on the control of droplets [108,109] yet its effect on bubbly flows is not yet fully understood [110,111,112,113]. Preliminary experiments at the University of Houston have demonstrated that the bubble dynamics can be effectively controlled by EW and that nucleate boiling heat transfer can be favorably improved over the entire range of boiling regimes.…”

However, electronic performance is closely related to operating temperature and thus improvements in cooling systems can greatly improve the performance of many components. The e ects of digitized heat transfer using electrowetting on a dielectric were investigated in this paper. It was found that droplets maintained higher Nusselt numbers than continuous low and exhibited oscillations correlated to the circulation length which dampened out over time. Furthermore, droplets displayed heat transfer characteristics that were heavily dependent on the aspect ratio of the droplet where higher aspect ratios exhibited higher Nusselt numbers. In all cases, droplet Nusselt number was greater than the continuous Graetz ow. Using the results found here, droplet paths

“…This subfield of microfluidics is often termed digital microfluidics. Digitized heat transfer on the basis of EWOD was proposed by Mohseni and Baird [31,32]. In comparison with pressuredriven flow in microchannels, the digital approach could avoid high pressure problems, which is encountered in pressure-driven flow in microchannels at high flow rates.…”

Heat transfer in segmented flow in microchannels can be significantly enhanced by recirculating vortices, due to the presence of interfaces. The processes of heat transfer in segmented flow subjecting to asymmetric boundary conditions are studied. Two types of boundary conditions are considered, asymmetric constant surface temperature and asymmetric constant surface heat flux. The paths of heat flow and the effects of the thermal conductivity, the plug length, and the Peclet number are studied.The results show different features from those at symmetric boundary conditions. The heat transfer process at asymmetric boundary conditions is controlled by both thermal advection and diffusion at the mid-plane of the channel. The coupling effects between the adjacent plugs complicate the process by the heat transfer across plug-plug interfaces.
