Investigation of interface erosion rate by Jet Erosion Test and statistical analysis [PDF]

open access: yesEuropean Journal of Environmental and Civil Engineering, 2011
L'érosion est l'une des principales causes d'instabilités d'ouvrages hydrauliques en terre. Deux types d'érosion peuvent être distingués: la suffusion et l'érosion d'interface. Cet article porte sur l'érosion d'interface et le Jet Erosion Test est utilisé afin d'évaluer la sensibilité à l'érosion de sols fins.

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

open access: yesEnergies, 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.

Erosion Test of Metals by Water Jet

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1943
円筒型の試驗片を4箇回轉円板の周りに取付けこれを種々の回轉速度にて廻し、別にノズルより4mm径の水柱を噴射させこれを試驗片が切る様にした装置にて各材質の耐蝕性を試驗したものである。試驗した材質は不銹鋼、不銹鋳鋼、マンガン鋳鋼、鋳鋼の4種である。耐蝕性の強い順位は不銹鋼、不銹鋳鋼、マンガン鋳鋼、鋳鋼の順となる。
