英文摘要	Electrostatics is an inevitable phenomenon in fluidization processes and granular flow, where collisions between particulates and walls with different materials occur. In this work, a two-dimensional computational fluid dynamics model based on the Eulerian-Eulerian approach was applied and coupled with a first-principles electrostatic model to describe the gas-solid two-phase flow behavior in a fluid catalytic cracking (FCC) riser reactor under the electrostatic conditions. The coupled model was used to predict the main gas-solid fl ow distribution parameters in the FCC riser, such as electric potential, particle volume fraction, gas-phase temperature, and gas-phase component fractions. The simulation results showed that the electrostatic had a significant influence on the particle distribution in the bottom dense region of the FCC riser, whereas it had a weak influence in the upper dilute region at the cold-flow conditions. The simulation results also showed that the electrostatic had a weak influence on the particle concentration, gas-phase temperature, and lump concentration distributions when the cracking reaction was considered. ? 2014 Curtin University of Technology and John Wiley & Sons, Ltd.
