| dc.description.abstract | In this dissertation, we investigated the electrokinetics and mixing in a charged modulated microchannel caused by an applied pressure gradient and electric field. We discussed electrokinetic transport effects under the application of combined pressure and dc electric fields for different values of electric double layer thickness and channel patch potential using detailed numerical simulations based on the coupled Poisson, Nernst–Planck, and incompressible Navier–Stokes equations. We examined the rise in fluid flow velocity in elctro-osmotic flow with increasing pressure gradient in flow direction and reduction in flow velocity with increasing pressure gradient in opposing flow direction. We investigated how variations in pressure gradient size and direction impact potential distribution and fluid velocity. We evaluated potential distribution and fluid velocity over the electric double layer for various debye length values.Using the requisite parameters, we solved the Poisson boltzmann equation for electroosmotic flow in a charged slit micro-channel. For given parameters and conditions, we estimated fluid velocity using a modified Navier stokes equation. We also spoke about the boltzmann distribution and the nernst plack equation, which are needed to solve the Poisson-Boltzmann equation. | |
