Analytical determination of electric voltage for pressure-driven flow through complex microchannels

An analytical determination of electric voltage generated by the pressure-driven flow through complex microc hannels was analyzed based on the fractal theory. The pressure-driven flow through a complex micro channel with consideration of electrokinetic phenomena is describedby the momentum and Poisson-Boltzmann (P-B) equations. The solution of induced electric field strength and electric voltage across complex micro channels are obtained using the fractal theory and technique, which are the function of dimensionless electroosmotic radius and the porosity. The results obtained show that the analytical results are agreed well with the experimental data. © 2013 Binary Information Press & Textile Bioengineering and Informatics Society.
