This paper describes a 3-D developing flow model by using Navier stoke equations with electric double layer (EDL) effect to model the flow field in microchannel. The electric potential distribution is simulated using a Poisson-Boltzmann equation. Results comparing the performances of the microchannel under different nondimensionalized electric potential are shown and discussed. Nusselt numbers for each case such as with or without EDL effect is also calculated; so that the actual effectiveness of the micro-channel can be understand.Keywords:numericaldeveloping flowmicrochannelEDLNavier-Stoke References G.
