Analysis of the velocity distribution in the UVC module

Abstract

The study presents the capabilities of the AutoCad CFD 2016 program as an auxiliary tool in the design of indoor air purification devices. The purpose of this work was to verify the location of UVC lamps and the elements enabling equal distribution of the air in the sterilisation module. The analysis was carried out in two-dimensional space. Three air streams of 100, 200 and 300 m3/h were assumed. The research considered the construction of a module with three and four UVC lamps in different configurations and with the module being additionally equipped with an injector, a steering device, an injector and a stream obstructer. The results suggest that the equal air distribution in the module is guaranteed with the variation of 4 UVC lamps additionally equipped with the injector and steering device at the angle of 30o, as well as the variation with the injector and stream obstructer with the height of 9.5 mm.
