Abstract

The determination of temperature distributions, maximum temperatures, and hot spot locations in photochemical reactors is of considerable importance in their design and operation. In the present work, we compute the temperature field in a laminar flow circular tube photoreactor subjected to an azimuthally uniform, radially incident monochromatic light source. The most interesting result concerns the movement of the hot spot away from the centerline and towards the wall as the optical density (OD) increases. The results show that there is a critical value of the optical density, depending on the Peclet number below which the hot spot is located on the center-line, and above which the hot spot begins to move toward the wall.
