Abstract
This paper investigates the flow field, the light intensity distribution and the distribution of organism concentration with UV disinfection in a chamber. The commercial software FLUENT 6.3 has been employed to solve the continuity, velocity and turbulence equations. Turbulence is described by the standard k-å turbulence model. P-1 method has been employed to solve the radiative transfer equation. The obtained incident radiation is used to compute the inactivation term in the species equation. The results show the ventilation has a significant effect on the distribution of the microorganism concentration.
