Research on Cavitation Wake Vortex Structures Near the Impeller Tip of a Water-Jet Pump

Energies, 2023
Cavitation can cause noise in the water-jet pump. If cavitation occurs in the water-jet pump, the hydraulic components in the pump are prone to erosion. The surface erosion reduces energy delivery efficiency and increases maintenance costs.

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 ...

The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy [PDF]

, 2011
Recent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue

Experimental and Numerical Investigation of Tip Leakage Vortex Cavitation in Water-jet Pump [PDF]

Journal of Applied Fluid Mechanics
During the operation of a water-jet pump, cavitation generates noise and vibration, causes surface erosion of the hydraulic components, and reduces the performance of the pump.

Erosion due to impingement of cavitating jet.

Hydraulics & Pneumatics, 1987
Cavitation erosion produced by impingent of cavitating jet was experimentally studied with specimens of aluminum alloy in high water base fluid of chemical solution type and tap water. Furthermore, the behavior of impinging cavity clouds was observed through instantaneous photographs.

Dynamics of cavity structures and wall-pressure fluctuations associated with shedding mechanism in unsteady sheet/cloud cavitating flows

Flow, 2023
The physics and mechanism of sheet/cloud cavitation in a convergent–divergent channel are investigated using synchronized dynamic surface pressure measurement and high-speed imaging in a water tunnel to probe the cavity shedding mechanism.

Appearance of high submerged cavitating jet: The cavitation phenomenon and sono luminescence [PDF]

Thermal Science, 2013
In order to study jet structure and behaviour of cloud cavitation within time and space, visualization of highly submerged cavitating water jet has been done using Stanford Optics 4 Quick 05 equipment, through endoscopes and other lenses with Drello3244 and Strobex Flash Chadwick as flashlight stroboscope.
