“…elliptical geometry, multilamp reactors, etc.) that can be found in literature (Alfano, Vicente, Esplugas, & Cassano, 1990;Esplugas, 1983).…”

Modeling of Gas-Phase Photodegradation of Chloroform and Carbon Tetrachloride

“…Many research groups have contributed to the development of light distribution models that describe the irradiation field inside the homogeneous reactors based on some theoretical assumptions; however, the most frequently used models are the line source spherical emission (LSSE), 8 the diffused line source emission (DLSE), 9,10 and the extense source with volumetric emission model (ESVE). 18,19 It was found in an earlier study that all three models predict quite accurately the irradiance along the radius and no model has apparent advantages over other models. 20 However, because of a complex algorithm, the ESVE model takes much longer computational time to converge; thus, in this study, the two simple line source models are employed to evaluate the radiation field.…”

Advanced Oxidation Processes

“…Many designs of photoreactors are found in the literature: (a) annular reactors, (b) flat-tray reactors, (c) "merry-go-round" reactors, (d) collimated beam reactors, (e) single lamp multitubular reactor, and (f) multilamp tubular reactor (27)(28)(29). Annular photoreactors where the UV lamp is mounted inside the inner annulus of the reactor are more commonly used, and a typical diagram (applied for the gas phase UV-oxidation) is shown in the following figure.…”
