Based on the incompressible Navier Stokes equation (N-S) and coupling principle of laminar flow electric field, a new 3D electroosmotic micromixer with variable module is designed in this paper. A microchannel throughout to improve mixing efficiency. The efficiency different directions, positions, alternating voltages times was studied. It can be seen from simulation results that under influenc...

In the last twenty years, application of microreactors in chemical and biochemical industrial processes has increased significantly. The use microreactor systems ensures efficient process intensification due to excellent heat mass transfer within microchannels. Monitoring concentrations microchannels is critical for a better understanding physical occurring micromixers microreactors. Therefore,...

This paper presents and compares two different strategies in the numerical simulation of passive microfluidic mixers based on chaotic advection. In addition to flow velocity field calculations, concentration distributions of molecules and trajectories of microscale particles were determined and compared to evaluate the performance of the applied modeling approaches in the proposed geometries. A...

Two novel passive micromixers, denoted as the Y-Y mixer and the H-C mixer, based on split-and-recombine (SAR) principle are studied both experimentally and numerically over Reynolds numbers ranging from 1 to 100. An image analysis technique was used to evaluate mixture homogeneity at four target areas. Numerical simulations were found to be a useful support for the design phase, since a general...

As micromixers offer the cheap and simple mixing of fluids suspensions, they have become a key device in microfluidics. Their performance can be significantly increased by periodically varying inlet pressure, which leads to non-static flow improved process. In this work, micromixer with T-junction meandering channel is considered. A periodic pulse function for pressure numerically optimized reg...
