Abstract

We present here a pretty simple method for matching the indices of refraction between a solid and a liquid, which is needed for flow visualization inside porous media. With this technique, a matched medium, consisting of Duran glass beads and a mixture of Dow Corning 550 and Dow Corning 556 is made. Experiments are conducted in an open channel with a porous bed and overlying fluid to investigate fluid dynamics in the interface region of fluid and porous. Using Particle Image Velocimetry, flow fields both in the fluid region and within porous region are obtained.
