Abstract

A micro PIV system has been developed as a new diagnostic tool for micro scale flow and applied to the measurement of microchannel flow. The micro PIV system employs the incident-light fluorescent microscope system and utilizes high-power pulsed Nd:YAG lasers, a high-resolution CCD camera and 1 μm diameter fluorescent tracer particles. The velocity distributions of pressure-driven flow and pressure- and electrokinetically-driven flow in a microchannel were measured using the micro PIV system and the visualization of flow fields in a microchannel was demonstrated.
