    ABSTRACT: Being able to accurately predict the performance and operation of multiphase flow systems continues to be a significant challenge. In order to continue the advancement of knowledge and to develop better models, a 10 cm diameter fluidized bed of 185 μm glass beads was used along with an Electrical Capacitance Volume Tomography (ECVT) sensor and high speed pressure measurements. Three dimensional images of the gas–solid flow structure were obtained and analyzed as well as frequency information from the high speed pressure transducers. The experimental data was then compared to four computational models performed with CPFD Software’s Barracuda code exploring different techniques to handle the perforated distributor plate.

    The Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has a mission to improve the efficiency, reliability, and environmental performance of coal-fueled power-generation systems. As part of this mission, NETL’s Advanced Research program has selected Tech4Imaging, with collaboration from The Ohio State University (OSU), to develop an imaging system for large-scale, cold-flow circulating fluidized beds (CFB).
