Abstract

This work describes a steady two-dimensional flow model together with an associated disinfection model. The commercial software FLUENT 6.3 has been employed to solve the continuity, velocity and turbulence equations. Turbulence is described by low Reynolds number k-ε turbulence model and Standard k-ε turbulence model, respectively. 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 CFD modeling results are in good agreement with the existing experimental data for the UV channel. For the flow field, the low-Reynolds number k-ε model is superior to the standard k-ε model. The approach velocity has a significant effect on the disinfection efficiency. The organism concentration at the outlet decreases fast to a low inlet velocity.
