    Abstract

    The radiation field of a packed-bed photocatalytic reactor filled with quartz wool coatedwith titanium dioxide was modeled using the Monte Carlo technique and the followinginformation: the radiation flux emitted by the lamps, the diameter size distribution ofthe quartz fiber cloth, the mass of quartz fibers and of TiO2 that was immobilized on thefiber surface as well as the refractive index and the spectral absorption coefficient of thematerials of the system. Modeling predictions were validated with radiometermeasurements of the transmitted radiation through the reactor, the root mean squareerror being < 9.7%. Finally, by means of a parametric study, the validated model wasused to analyze the effect of the design variables: the radii of the quartz fibers,thickness of the TiO2 coatings, and amount of TiO2 coated quartz wool, on thedistribution and nonuniformity of the radiative energy distribution inside the reactor.
