In this paper, we describe experimental results of PIV (Particle Imaging Velocimetry) technique applied to visualize flow in microchannels. 100μm width×60μm height channels were fabricated with PDMS transparent silicone rubber, and 1μm diameter fluorescent particles were used for tracers. Flow visualization was successfully carried out, and large disturbance of flow velocities caused by interaction of gas-liquid interface and a trapped liquid droplet at corners were observed. Relatively large focal length and Brownian motion of the tracer particles are found to be serious problems on micro-PIV techniques.
