Combined wear of slurry erosion, cavitation erosion, and corrosion on the simulated ship surface

open access: yesAdvances in Mechanical Engineering, 2019
The surface material of marine ship hulls suffers degradation by slurry erosion because of the impact of sands or solid particles in seawater. When the ship’s moving speed increases, pressure is changed suddenly and cavitation erosion will occur ...

The design and performance of gear pumps with particular reference to marginal suction condition [PDF]

open access: yes, 1989
In this thesis an investigation for the identification, measurement and modelling of the gear pump performance under marginal suction condition, created in the suction line and resulting in cavitation at the suction port and cavitation erosion on the ...

Objective Measurement of Tooth Color Using Spectrophotometry and ICDAS: Quantifying CIELAB Color Changes Across Caries Severity

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The International Caries Detection and Assessment System (ICDAS) is widely used for early caries detection but relies on visual interpretation. Although spectrophotometry objectively quantifies tooth color, variation across ICDAS categories and its relationship with lesion severity remain unclear. The present in vitro study therefore

Exploration of cavitation-induced erosion metrics in throttle flow simulations

open access: yes, 2018
Although there have been extensive experimental and computational investigations in characterizing cavitation phenomenon in both diesel and gasoline direct injectors, much is still unknown about the mechanisms driving cavitation-induced erosion, and ...

In Vitro Aligners Force Analysis in the Maxillary Arch During En‐Masse Retraction With Different Attachment Positions

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to analyse the three‐dimensional forces acting on maxillary teeth with aligners activation of en‐masse retraction based on the different attachment positions in vitro. Methods Three groups were designed for the same 0.25 mm en‐masse retraction forces with three different attachment positions.

Hydrodynamic Mechanisms in Cavitation Erosion [Elektronisk resurs]

open access: yes, 2012
A refined description of the hydrodynamic mechanisms involved in determining the erosiveness of a collapsing cavity is presented. It highlights the impact of the possible presence of a partially glassy sheet and that collapse symmetry/asymmetry needs to ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Cavitation of refratory samples based on talc and domestic zeolite [PDF]

open access: yesTehnika, 2018
Using domestic zeolite from Igroš as row material for ceramic samples for application in condition of cavitation erosion. Samples based on talc with 15 % of zeolite, from Igroš, sintered at 1200oC were used in this investigation. The ultrasonic vibratory

Sustainable design and durability of domestic micro combined heat and power scroll expander systems.

open access: yes
Research to understand the mechanisms of wear within the main components of three different micro-CHP scroll expander systems was conducted. This was performed in order to identify the possible tribo-mechanical effects (abrasion, adhesion, cavitation ...
