Abstract

The interface between intersecting microfluidic multicomponent flow is investigated experimentally. The system studied has a main channel and an intersecting (at 90 degrees) daughter channel and the fluid is a water-microsphere mixture. Flow visualization is achieved using confocal fluorescence microscopy. Microsphere solutions of 2% and 4% spheres (by weight) are investigated and compared to each other as well as all water flows. A three-dimensional rendering of the location and shape of the interface at the junction for different flow ratios (daughter flow to total) is examined for a combined flow Reynolds number of approximately one. The interface downstream of the junction is reasonably planer (two-dimensional) and the presence of microspheres does not appear to strongly influence the location of the flow interface.
