Comparative analysis of counter-current and co-current downer reactors using particle image velocimetry and computational particle-fluid dynamics

Comparative analysis of counter-current and co-current downer reactors using particle image velocimetry and computational particle-fluid dynamics

We investigated the hydrodynamics in co- and counter-current downer operations using particle image velocimetry (PIV) and computational particle fluid dynamics simulations (CPFD). Pilot-scale experiments were conducted for fluid catalytic cracking (FCC) catalysts and sand, which verified the system...
