Computational Fluid Dynamics in Drinking-Water Treatment

Computational fluid dynamics (CFD) modeling of VUV/UV photoreactors for water treatment

“…Complete modeling of the VUV/UV process involves the simultaneous resolution of the local transfer equations of momentum, mass, and radiative energy (for UV and VUV radiations), along with a complex kinetic scheme with more than 40 reactions [6]. Computational Fluid Dynamics (CFD) is an established and effective tool for modeling complex processes, and has been used extensively in recent years for the design, optimization and scale-up of UV disinfection and oxidation photoreactors [7][8][9][10][11][12][13]. All studies indicated the importance of using a comprehensive kinetic scheme along with a detailed radiation model including the reflection/refraction/absorption of photons in the UV photoreactor.…”
