Simulation of a Multi-annular Photocatalytic Reactor for Degradation of Perchloroethylene in Air: Parametric Analysis of Radiative Energy Efficiencies

A multi-annular photocatalytic reactor was designed, that shows good effectiveness for perchloroethylene (PCE) removal from contaminated air streams. In a previous work, a rigorous physical and mathematical model of the photocatalytic reactor was developed and experimentally verified. In this work,...
