Abstract

Using the Extense Source Formulation (Irazoqui et al., 1973a), a radiation distribution model for the tubular lamp-elliptical reflector system was developed for predicting energy density profiles inside the elliptical cavity of the system.

It introduces a significant improvement over the linear-lamp models since it avoids any form of singularities in the prediction of radiation energy density profiles at the focal points of the elliptical reflector. Also, all lamp and reflector dimensions are parameters of the model.

Calculated results agree well with published experimental data for a similar lamp reflector set up.

One of the most important conclusions is the absence of uniform irradiation from all radial directions at the reactor location.
