Modeling the electrostatic effect on the hydrodynamic behavior in FCC risers: From understanding to application

- Electrostatic effect in FCC risers was studied by CFD simulation coupled with electrostatic model.
- The coupled model was verified using open experimental data.
- Simulation results demonstrated obvious electrostatic effects in FCC risers.
- Electrostatic effect in small-scale FCC risers was stronger than their large-scale counterparts.
- External electric field may be applied to tailor the flow field in FCC risers.
