Experimental study of cavitation intensity using a novel hydrodynamic cavitation reactor
Journal of Mechanical Science and Technology, 2019The cavitation intensity of a novel hydrodynamic cavitation reactor (HCR) was experimentally evaluated in terms of the amount of bubble generation and bubble collapse energy. The amount of bubble generation was analyzed by flow visualization using a high-speed camera. The bubble collapse energy was evaluated by calculating the generated thermal energy.

CFD-assisted modeling of the hydrodynamic cavitation reactors for wastewater treatment — A review
Journal of Environmental Management, 2022Hydrodynamic cavitation has been a promising method and technology in wastewater treatment, while the principles based on the design of cavitational reactors to optimize cavitation yield and performance remains lacking. Computational fluid dynamics (CFD), a supplementation of experimental optimization, has become an essential tool for this issue, owing

AbstractThis paper presented an addendum rotational hydrodynamic cavitation reactors (ARHCR) that enabled circumferential shear cavitation, axial cavitation, and the Venturi effect, thus increasing cavitation efficiency. The experiments on hydroxyl (·OH) release and chemical oxygen demand (COD) removal demonstrate the feasibility of cavitation ...

Hydrodynamic Cavitation Reactor for Efficient Pretreatment of Lignocellulosic Biomass
Industrial & Engineering Chemistry Research, 2016In the present study, hydrodynamic (HD) cavitation was combined with sodium percarbonate (SP) for the pretreatment of lignocellulosic biomass. For HD cavitation, a circular flow system equipped with a venturi tube was employed. The combined system of HD and SP (HD-SP) was compared to a pretreatment system using ultrasonication and SP (US-SP).

Numerical Assessment of Hydrodynamic Cavitation Reactors Using Organic Solvents
Industrial & Engineering Chemistry Research, 2011This paper attempts to give a physical insight into the behavior of cavitation bubbles in a hydrodynamic cavitation reactor, with organic liquids employed as the bulk medium. The diffusion limited model of cavitation bubble dynamics has been coupled to hydrodynamics of flow through an orifice.
