CFD modelling of an immobilised photocatalytic reactor for phenol degradation

Abstract Photocatalysis is an advanced oxidation process, which has been gaining attention as a sustainable technology for tackling pollution. Optimum design, fabrication and scaling up of novel photocatalytic reactors are faced with problems such cost numerous experimental trials optimisation. Computational fluid dynamics (CFD), computer simulation technique can ease the process reactors. The current study focuses on CFD modelling serpentine flow path reactor curved baffles phenol degradation. investigation compared different configurations to finalise optimum design maximum removal efficiency. Initially, simple cuboidal was chosen efficiency 27%. However, being introduced, displayed improved 42%. addition homogeneity degradation showed that increased residence time mixing, while prevented channelisation enhanced Efficiencies corresponding baffle types geometry were also final horizontal baffled rate 0.3 L/s 43.1% 18.44 s.
