A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers.
