Chemistry Induced by Hydrodynamic Cavitation
Journal of the American Chemical Society, 1997Cavitation (the formation, growth, and implosive collapse of gas or vapor-filled bubbles in liquids) can have substantial chemical and physical effects. While the chemical effects of acoustic cavitation (i.e., sonochemistry and sonoluminescence) have been extensively investigated during recent years,1-5 little is known about the chemical consequences ...

Cavitation Generation and Usage Without Ultrasound: Hydrodynamic Cavitation
2010Hydrodynamic Cavitation, which was and is still looked upon as an unavoidable nuisance in the flow systems, can be a serious contender as an alternative to acoustic cavitation for harnessing the spectacular effects of cavitation in physical and chemical processing.

Light Emission from Hydrodynamic Cavitation
The Physics of Fluids, 1967The characteristics of light emission from hydrodynamic cavitation are given. Changes were examined for small variations in water temperature, pressure, and gas content. Using oxygen, nitrogen, and xenon dissolved in water, the shapes, intensities, and pulse height spectra for individual light pulses were determined.

Engineering design methods for cavitation reactors II: Hydrodynamic cavitation
AIChE Journal, 2000AbstractThe bubble behavior and hence the pressure generated at the collapse of the cavity for hydrodynamic cavitation depends on the operating conditions and geometry of the mechanical constriction generating cavitation. The effect of operating parameters such as inlet pressure through the system's orifice, initial cavity size, and the indirect effect

Application of Hydrodynamic Cavitation to Wastewater Treatment
Chemical Engineering & Technology, 2016AbstractHydrodynamic cavitation is a promising application in wastewater treatment due to its simple reactor design and capacity in large‐scale operation. Theoretical studies including the basic mechanism of pollutant degradation, modeling of pressure distribution in the cavitation reactor, and bubble dynamics models coupled with chemical reactions are

Compressible Fluid Model for Hydrodynamic Lubrication Cavitation
Journal of Tribology, 2013In this paper, it is shown how vaporous cavitation in lubricant films can be modeled in a physically justified manner through the constitutive (compressibility) relation of the fluid. The method treats the flow as a homogeneous mixture employing a “void fraction” variable to quantify the intensity of cavitation.

Hydrodynamic Processes Controlling Cavitation Erosion
2014In this paper we consider development of cavitation erosion having its origin in the sheet cavitation on the hydrofoils and propeller blades. The discussion includes generation of cloud cavitation by processes related to sheet cavity dynamics and how a cloud collapse can be enhanced by energy cascading from the collapse of a sheet cavity into the ...

Solvent degradation studies using hydrodynamic cavitation
Environmental Progress & Sustainable Energy, 2017Hydrodynamic cavitation for the degradation of organic solvents was investigated in detail using a newer form of cavitating device‐vortex diode. The results were also compared with that using conventional cavitating device orifice. Removal of three different organic solvents—acetone, methyl ethyl ketone (MEK), and toluene were studied on a pilot plant ...

Neutron Emissions from Hydrodynamic Cavitation
During the last few years, some investigators reported interesting results regarding neutron emissions from ultra-sonic cavitation in liquids and solids. In the present paper, the described experiments were conducted in order to evaluate neutron emissions from liquids subjected to hydrodynamic cavitation by an hydraulic circuit prototype. In particular,A. Manuello +4 more
