It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.

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. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.
