“…The EOF can not only eliminate the need for mechanical micropumps but is also easy to control and operate, which has been widely used in fields such as lubrication [22], micromixers [23], and micropumps [24]. The transportation efficiencies of EOF alone and when combined with pressure-driven flow (PDF) within microchannels have been extensively researched [25][26][27][28][29][30][31][32][33]. For example, Dutta et al [25] established a mathematical model to address the temperature, Nusselt number, and convective heat transfer coefficient of the steady EOF with a random pressure gradient in a two-dimensional parallel microchannel.…”

Building upon the efficient transport capabilities observed in the fractal tree-like convergent structures found in nature, this paper numerically studies the transport process of the combined electroosmotic and pressure-driven flow within a fractal tree-like convergent microchannel (FTCMC) with uniform channel height. The present work finds that the flow rate of the combined flow first increases and then decreases with the increasing branch width convergence ratio under the fixed voltage difference and pressure gradient along the FTCMC, which means that there is an optimal branch width convergence ratio to maximize the transport efficiency of the combined flow within the FTCMC. The value of the optimal branch convergence ratio is highly dependent on the ratio of the voltage difference and pressure gradient to drive the combined flow. By adjusting the structural and dimensional parameters of the FTCMC, the dependencies of the optimal branch convergence ratio of the FTCMC on the branching level convergence ratio, the length ratio, the branching number, and the branching level are also investigated. The findings in the present work can be used for the optimization of FTCMC with high transport efficiency for combined electroosmotic and pressure-driven flow.
