Bacterial Sterilization Using Cavitating Jet
Journal of Fluid Science and Technology, 2007 In this paper, a new sterilization method using cavitating flow is presented. Water with bacteria was pressurized up to 105 MPa and flushed out through two very small nozzles 0.1-0.31 mm in diameter, where a cavitating jet was generated containing ...

Destruction of Plankton using Cavitating Jet
Journal of Fluid Science and Technology, 2008 This paper presents the experimental result of the destruction of plankton using a cavitating jet generated by a two-dimensional nozzle. The destruction rate of plankton increased with the jet velocity and it reached almost 100% when the nozzle velocity ...

Shadowgraph Imaging of Cavitating Jet
Journal of Flow Control, Measurement & Visualization, 2015 This paper deals with the statistical properties of unsteady structure of cavitating water-jet issuing into a stagnant fluid of water using the shadowgraph imaging combined with the proper orthogonal decomposition (POD) analysis. The experimental result indicates that the cavitating jet is composed of axisymmetric mode, while the periodic axial ...

The Generation Methods and Applications of Cavitating Jet by Using Bubble Collapse Energy
EnergiesCavitation is a dynamic process characterized by the formation, growth, and collapse of vapor or gas vacuoles in liquids or at the liquid–solid interface, initiated by a local pressure drop.

Sonoporation from Jetting Cavitation Bubbles [PDF]
Biophysical Journal, 2006 The fluid dynamic interaction of cavitation bubbles with adherent cells on a substrate is experimentally investigated. We find that the nonspherical collapse of bubbles near to the boundary is responsible for cell detachment. High-speed photography reveals that a wall bounded flow leads to the detachment of cells. Cells at the edge of the circular area

Visualization of cavitating micro jets [PDF]
EPJ Web of Conferences, 2012 The paper deals with one experimental set up integrated for research of the cavitating micro flows, which is incipient behind the micro channel or micro discharge nozzle outlet port. Experimental system is integrated from three major systems: hydraulic circuit with installed discharge nozzle (or micro channel), subsystem for data acquisition and data ...

Cavitation Induction by Projectile Impacting on a Water Jet [PDF]
, 2019 The present paper focuses on the simulation of the high-velocity impact of a projectile impacting on a water-jet, causing the onset, development and collapse of cavitation. The simulation of the fluid motion is carried out using an explicit, compressible,

Study of the cavitating instability on a grooved Venturi profile [PDF]
, 2013 Cavitation is a limiting phenomenon in many domains of fluid mechanics. Instabilities of a partial cavity developed on an hydrofoil, a converging-diverging step or in an inter-blade channel in turbomachinery, have already been investigated and described ...
