The rectification of electro-osmotic flows is important in micro- and nano-fluidics applications such as micropumps energy conversion devices. Here, we propose a simple diode which colloidal particles are contained between two parallel membranes with different pore densities. While the flow forward direction just pushes toward high-pore-density membrane, backward blocked by near low-pore-densit...

An investigation of water transport across the membrane of a proton exchange membrane fuel cell is performed to gain further insight into water management issues and the overall behavior of a representative phenomenological model. The model accounts for water transport via electro-osmotic drag and diffusion and is solved using a finite volume method for a one-dimensional isothermal system. Tran...

The in vitro fabrication of big osteoarticular implants integrating biomaterials and cells is tremendous interest because these tissues have a limited ability to regenerate. However, the growth such highly problematic, especially later culture, when extracellular matrix has almost filled initial porous network. Thus, fluid flow required properly perfuse sample cannot be obtained by hydraulic dr...

We present a numerical study of induced-charge electro-osmosis (ICEO) of electrolytes in microfluidic channels containing a fixed dielectric structure. ICEO is the nonlinear electro-osmotic slip that occurs in the electrolyte when an applied electric field acts on the ionic charge it induces around the polarizable surface of the dielectric structure. We also establish a method for optimizing th...

Modeling and simulation for heat and mass transport in micro channel are beingused extensively in researches and industrial applications to gain better understanding of thefundamental processes and to optimize fuel cell designs before building a prototype forengineering application. In this study, we used a single-phase, fully three dimensionalsimulation model for PEMFC that can deal with both ...

Abstract In this article, we consider the flow of a Burgers’ fluid transient electro-osmotic type in small tube with circular cross-section. Analytical results are found for velocity and, electric potential profile by solving Navier–Stokes and linearized Poisson–Boltzmann equations. Moreover, these equations solved help integral transform method. We cases which changes time those does not chang...
