Flow past objects in the microchannel are used to disturb the flow and thereby achieve adequate mixing. A three-dimensional numerical investigation has been carried out to analyze the flow characteristics around an elliptical rib with various aspect ratios (AR) ranging from 0.4 to 0.6, where the major axis was aligned parallel to the free stream.
