The foonation of water drops of specific size when sheared by a tetradecane stream at a T-junction in a microchannel was investigated numerically. The numerical results showed that the water drop sizes decreased with increasing tetradecane flow rate and decreasing interfacial tension. This is in agreement with published experimental results. During the formation of the water drops, two recirculating zones are formed in the water stream, a large one occupying most of the water drop, and a smaller one near the downstream corner of the T-junction. The smaller recirculating zone results in a high pressure spot.
