Study of the Effects of Electrokinetic Field on Heat Transfer through Rectangular Microchannels

In this study fluid flow and heat transfer in a microchannel in presence of EDL is studied. To avoid the complication due to cross-section geometry and the surface roughness of the flow channels, a microchannel formed by two parallel, smooth silicon plates were used. Solution of Poisson-Boltzman in the channel gives electrical potential distribution in cross section of the channel. Then after using the electrical potential distribution in the channel, the electro-kinetic field has been determined. Electro-kinetic field is used in momentum equation as a term of body force. For solving the momentum equation velocity distribution in the channel is determined. Finally using velocity distribution, energy equation is solved and temperature contour and Nusselt number in channel is calculated.
