Production, distribution and interaction of droplets in microchannels

The interest on drop formation at the miscroscale is growing since some years. Chemical, biological as well as from basic science applications make use of microdroplets. In this work, we have investigated the production of drops in a T-juncture configuration. By varying the flowrates, the viscosities and the geometry different lengths of drops were obtained. Vaseline as carrier and glycerol solutions (drops) have been used to produce them. The stability and distribution of drops at a X joint channel intersection has been studied as a function of the length of the drops and the angle of the joint and the impedance of the outlet channels. Our study shows that a little change (of the order of 10%) on the impedance of the channels would be enough to control satisfactorily the distribution of drops.
