Abstract
Photochemical and photocatalytic reactors are being widely used in the wastewater treatment and water/air purification. One of the popular reactor configurations for water purification is the multiple lamp tubular reactor. The efficiency of purification in a photoreactor is determined by the distribution of UV radiation within the tubular space. In this study, the light intensity distribution in a two-lamp photoreactor has been evaluated using a finite volume scheme (which is essentially a variant of the discrete ordinate model). The irradiated space was divided into a number of finite volumes and angles (directional discretisation). Simulations were performed for both homogenous and heterogenous (with titania catalyst) reactors. Contours of incident radiation and local volumetric rate of energy absorption were plotted and analysed. Model predictions were used to assess the effect of catalyst loading on the light intensity distribution inside various reactor configurations. The optimum value of the distance between lamps in a 2-lamp photoreactor was found to be dependent on the optical properties of the photocatalyst used. Model predictions were found to match-well qualitatively with the published data from the literature.
