Investigation on the characteristics of an advanced rotational hydrodynamic cavitation reactor for water treatment

Carbon Nanomaterials From Metal-Organic Frameworks: A New Material Horizon for CO2 Reduction

“…MOFs can be assembled by metal ions/clusters and organic linkers through coordination bonds by hydrothermal (Chen et al, 2020 ), microwave (The Ky et al, 2020 ), electrochemical (Vehrenberg et al, 2020 ), ultrasonic (Zhao et al, 2020 ), or hydrodynamic cavitation methods (Aiyappa et al, 2019 ; Kim et al, 2020 ; Sun et al, 2020a , b ). Generally, the MOFs possess special properties, including porous structures and tunable chemical compositions which enable the desirable design of MOF-derived composites with high catalytic activity.…”

Experimental and numerical studies on the cavitation in an advanced rotational hydrodynamic cavitation reactor for water treatment

“…Though numerous application-based work has been published on ARHCRs, the amount and depth of the fundamental research on ARHCRs are still considerably limited [44] . Even though a number of researchers have investigated the cavitation flow in ARHCRs by experimental flow visualization [27] , [28] , [33] , [37] , [41] , [44] , [45] , [46] and computational fluid dynamics (CFD) [47] , their corresponding mechanisms, especially for interaction-type reactors (i.e., cavitation is generated by the interaction motion between the rotor and stator) [33] , [35] , [37] , [41] , [44] , [45] , are still not well understood. Specifically, no researcher has quantitatively analyzed the cavitation development process in accordance with the visualization results.…”

“…In order to solve the problems above, we present here combined experimental and numerical investigations of the cavitation flow characteristics of a typical interaction-type ARHCR which has been proposed in previous studies [34] , [44] . The changes in the cavitation pattern, area ratio, and sheet cavitation (SC) length resulting from the interaction of cavitation generation units (CGUs) were analyzed in accordance with the experimental flow visualization results.…”

A novel continuous hydrodynamic cavitation technology for the inactivation of pathogens in milk

“…Due to the unsatisfactory scalability of ACRs, and the low cavitation intensity generated by conventional HCRs (e.g., Venturi and orifice types), most research on cavitation pasteurization or sterilization has focused only on batch processing which is not suitable for industrial-scale applications. Recently, advanced rotational HCRs (ARHCRs) with different mechanisms of cavitation generation to conventional HCRs have shown treatment efficacy and economic benefits far beyond those of traditional devices for various applications [33] , [34] , e.g., removal of microorganisms [35] , [36] , waste-activated sludge (WAS) treatment [37] , [38] , [39] , [40] , organic wastewater treatment [41] , [42] , biofuel synthesis [43] , [44] , delignification [45] , fibrillation [46] , and intensification of biogas production [47] . The advent of ARHCRs allows for the continuous HC (CHC) treatment of liquid foods.…”
