In this paper, for better understanding the flow pattern regime and mixing efficiency in two different geometries of microchannels a Computation Fluid Dynamics (CFD) modeling was carried out. The micromixing efficiency of the microchannels was studied by adopting the Villermaux/Dushman reaction in the modeling. The main objective of this study is to illustrate the effect of microchannels geometry on micromixing performance from the fluid dynamics point of view. Comparison between the calculated relative segregation index from modeling results with experimental data revealed a reasonable agreement
