| Outline of Final Research Achievements |
We carried out 3-D visualization of digital holographic PTV to understand the complicated flow in a sphere-packed pipe (SPP) by using a refractive index-matching method with a water used as a working fluid, the spheres was made of MEXFLON, whose refractive index is the same as that of a water. Spheres coated with TiO2 are used in water-treatment photoreactors. A water-treatment reactor was constructed containing TiO2-coated spheres of the fluoropolymer MEXFLON, which has a refractive index identical to that of water. The performance of the reactor in water purification was examined by means of a recirculation experiment using an aqueous solution of methylene blue. The pseudo-first order rate constants on the MEXFLON beads was 3.8 times greater than that on glass beads, confirming the effectiveness of matching the refractive index of the spheres to that of water.
