초록
Industrial single photon emission computed tomography (SPECT) is an useful techniqueto investigate the dynamic behavior of process flow. In the present study, to evaluate the influenceof a void on the performance of industrial SPECT, industrial SPECT with various radioisotopesources and gas holdups was modeled by the Monte Carlo simulation. The results are very encouraging;that is, the void little influences the performance of industrial SPECT, which means thatindustrial SPECT could be a suitable tool to investigate the dynamic characteristics of the flow ina water-air phase process.
