查询词典 gas-jet

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.
