Silicon oil and deionized water were utilized as working fluids in continuous phase and disperse phase, respectively. In order to restrict the flow into the silicon oil, four types of obstacles are placed at outlet section of the channel with deionized water, which are a single square, a single triangle, double squares and double triangles. The flow visualization shows the deionized water intervenes into the silicon oil and breaks down into individual droplets, successfully. With different obstacles placed, the forming speed and size of droplets can be controlled; the length of droplet is reduced by 9 percent to 25 percent of which in prototype T-junction channel. In addition, due to lateral force discovered in cases of triangle obstacle(s), unsymmetrical obstacles will be suggested as next assignment to give us more understanding of the formation of droplet.
