Electroosmotic flow in microchannels is restricted to low Reynolds number regimes characterized by extremely weak inertia forces and laminar flow. Consequently, the mixing of different species occurs primarily through diffusion, and hence cannot readily be achieved within a short mixing channel. The current study presents a numerical investigation of electrokinetically driven flow mixing in mic...
A biologically-inspired micropumping model in a three-dimensional tube subjected to localized wall constrictions is given in this article. The present study extends our previous pumping model where a 3D channel with a square cross-section is considered. The proposed pumping approach herein applies to tubular geometries and is given to mimic an insect respiration mode, where the tracheal tube rh...
A method for MEMS macromodel development is presented which is based on a physical device description to obtain mathematical relations for the device operation. Since design and technology parameters are input parameters of the resulting model, this method is well suited for design studies. As a benchmark problem, we refer to the macromodel of a micropump driven by an electrostatically actuated...
Electroosmosis is one of the most used actuation mechanisms for microfluidics in current active lab-on-chip devices. It generated on induced charged microchannel walls contact with an electrolyte solution. Electrode distribution plays key role providing external electric field electroosmosis, and determines performance electroosmotic microfluidics. Therefore, this paper proposes a topology opti...
