Electrokinetic effects on the pressure driven liquid flow and heat transfer through rectangular microchannels are numerically simulated in this work. Electrical potential, velocity and temperature fields are all determined for hydrodynamically fully developed and thermally developing laminar flows subject to two sets of thermal boundary conditions. Also obtained are friction coefficients and Nusselt numbers for both cases with and without the electrokinetic effects. The electrokinetic effects are discussed for various channel sizes, various zeta potentials, different ionic concentrations and different thermal boundary conditions.
