"Understanding the Physics of Advanced Oxidation in a Venturi Reactor"

"This paper is part of a research activity concerning theoretical and experimental studies of cavitation as an . Advanced Oxidation Process in a convergent-divergent nozzle. The capability and peculiarities of this . technology in degrading organic pollutants in water effluents are addressed by theoretical and . experimental studies. Dosimetry methods for estimation of hydroxyl radical production are carried out . through p-nitrophenol degradation. Additionally, for investigating the phenomenology of Venturi oxidation, . a mathematical algorithm is proposed, which couples a microscopic approach (on single bubble dynamic . with chemical reactions) with a macroscopic one (nucleation of bubbles’ clouds). Experimental evidences . agree with numerical ones in identifying an optimum level of inlet fluid pressure, in producing the highest . experimental removal rate and the highest theoretical radicals’ production."
