Effect of Pressure, Feed Rate, and Abrasive Mass Flow Rate on Water Jet Cutting Efficiency When Cutting Recombinant Bamboo

BioResources, 2014
The impact of varying pressure, feed rate, and abrasive mass flow rate on the efficiency of an abrasive water jet cutting process was studied in this work. Recombinant bamboo samples with thicknesses of 5, 10, and 15 mm were cut by the abrasive water jet.

Development of a Novel Superhydrophobic Sawdust–Perspex Composite Disc for Efficient Oil–Water Separation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.

On-line Recycling of Abrasives in Abrasive Water Jet Cleaning

Procedia CIRP, 2014
AbstractThis paper reports a method of on-line recycling for abrasives while using abrasive water jet to clean components to be remanufactured. It uses a stirring overflow separator to realize the separation of abrasives and dirt. Abrasives are broken into pieces due to the impact in cleaning process, and the contamination cleaned off mingles with ...

Demolition performance of high-pressure water jet based on SPH coupling with FEM for hydraulic demolition robot

Advances in Mechanical Engineering
Due to the huge computational cost caused by using multi-layer particles to achieve continuous water jet, this work developed a numerical model adopting single-layer particles to realize the unrestricted long-time continuous water jet.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.
