Abstract

The NETmix is a mili-photoreactor that can be used for the photo-catalytic oxidation of volatile organic com- pounds (VOCs) dispersed in gaseous streams. The flow inside this type of reactor can be laminar or turbulent. In this work, the choice of turbulence model is investigated through computational fluid dynamics tools. Two k − ε approaches were analysed, for a flow with a Reynolds number of approximately 150. Both Standard k − ε and RNG k − ε returned similar results, with slightly greater conversion when employing RNG k − ε model.
