Simulations of Fluid Dynamics (CFD), radiation distribution and chemical reaction in the photoreactor

Abstract

Abstract The fluid dynamic mechanics, Computational Fluid Dynamics (CFD), has become a valuable engineering tool for predicting the fluid flow, the quantity of movement transfer, the matter transfer as well as chemical reaction kinetics, by solving the numerical program using the Fluent software. In this study, CFD was used for the fluid dynamics analysis and simulation with a laminar flow regime on the chemical reactions, which excite the catalyst by a light source. The mineral pollutant (Ni2+) is reduced to elemental state in the photoreactor to different designs and models by photocatalysis leading to nickel in the form of a changeless cluster (Nio) and hydrogen in the form of gas (H2).
