In this study, we have studied the effect of heat transfer and voltage on microchannel with electroosmotic flow. We have used the finite elements method to solve the Navier–Stokes equation, and an increase in temperature and velocity was found from the increased voltage. The increments of heat flux causes in increase of temperature with EDL effect. In general, we can note that two points are accurate, first, in the EDL region the velocity is formed, and then the maximum value of velocity reaches on outside the EDL with flat shape distributions for all selected cases. Second, the effects of viscosity and applied zeta potentials cause this velocity distribution of electroosmotic flow. The main objective of the simulation is to study the effect of electric magnetic in microchannel towards fluid flow profiles. The results shows that increasing voltage cause increase in velocity.
