Light Intensity in an Annular Photochemical Reactor

Abstract

To estimate the light intensity distribution and the volume-average light intensity in an annular photochemical reactor, a surface source light distribution model was proposed. It has been assumed for the model that radiation from a lamp surface which has a spherical light distribution characteristic reaches into the reactor.
The experimental results of light intensity distribution measured by a CdS cell agreed well with those from the model. Also, the average light intensity estimated from the photoreduction rate of potassium ferrioxalate was compared with the theoretical prediction. The scale-up experiments for exposure length of lamp and radial distance of reactor supported the validity of the model.
