Mesoscale Analysis of Cavitation and Cavitation Erosion [PDF]

, 2020
Cavitation is one of the most common types of damage in hydraulic and hydropower engineering projects. In 1941, the spillway of the Boulder Dam in the U.S. suffered cavitation and developed a deep cavitation pit of 35 m in length, 9.5 m in width, and 13.7 m in depth at the end of its ogee section as a result of the washing away of over 4500 m3 of ...

Cavitation erosion behaviour of MAB-CU4 alloy: influences of cavitation number, attack angle, time, and stand-off distance

Materials Research Express
The present study comprehensively examines the cavitation erosion behaviour of a manganese aluminium bronze alloy (MAB-CU4 alloy) as a function of several parameters (i.e., cavitation angle, cavitation number, time, and stand-off distance), particularly ...

Characterization of Macro/Microstructure and Corrosion Resistance of Austenitic Gas Tungsten Arc Welding Cladding

Advanced Engineering Materials, EarlyView.
Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

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 ...
