A parallel fully coupled implicit fluid solver based on a Newton–Krylov–Schwarz algorithm is developed on top of the Portable, Extensible Toolkit for Scientific computation for the simulation of microfluidic mixing described by the three-dimensional unsteady incompressible Navier–Stokes equations. The popularly used fractional step method, originally designed for high Reynolds number flows, req...

Currently, we are heading towards the period of nanotechnology which extends to many engineering disciplines. The necessity of its development is crucial to make life more convenient, to improve efficiency of each research field, and to integrate portable healthcare system. Thus, the next most important step is to develop a technology to meet the needs of both industry and research area [1]. He...

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...

This study presents an integrated microfluidic chip for non-immunologically determining the concentrations of albumin in clinical urine samples. This microchip integrates membrane-type micromixers and a fan-shaped micropump capable of simultaneously and precisely delivering assay reagents to react with 6 urine samples in one single operation. The experimental results show that the coefficient o...

In Microbial Fuel Cells (MFCs), a mass transfer impact might be larger than expected because it not only effects the mass transfer losses (substrate flux [1, 2] and removal of waste [2]), but also effects the activation losses (mediator [3-5]) and the ohmic losses (proton transfer [6]). However, the convection/diffusion of the reactant transport from the bulk (reactant transport), which can be ...
