Cylindrical droplet formation in a W/O (water in oil) system of microchannel was analyzed experimentally and theoretically. The microchannel shape was modified to generate smaller droplet based on theoretical model. Numerical and experimental investigations were carried out with the novel microchannel. It is found that generated droplet was almost the spherical shape, since the diameter was smaller enough than the depth of microchannel. The results indicated that 3-dimensional and more precise theoretical model should be applied to realize the smaller droplet generation.
