An Improved Air Film Model for Studying the Tilt Characteristics of Aerostatic Thrust Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, an improved mass‐spring model that treats the lubricating air film as distributed springs is proposed to calculate the static and dynamic angular stiffness of aerostatic thrust bearings. The proposed model refines the traditional mass‐spring model by introducing the spatially varying mechanical properties of the air film and the

Sanitary risk in the handling of home‐prepared enteral formulations: A cross‐sectional assessment of microbiological contamination and food safety

Nutrition in Clinical Practice, EarlyView.
Abstract Background Studies show increased use of home enteral nutrition (HEN) owing to its benefits. However, knowledge about the sanitary risks of handling home‐prepared formulas remains limited despite their high contamination rates. This study aimed to assess the sanitary risks in the handling of home‐prepared enteral formulations by analyzing ...

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them

People and Nature, EarlyView.
Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

Development of slurry jet erosion test rig – An aid to investigate erosion resistance of materials

Materials Today: Proceedings, 2021
Abstract Slurry erosion is a common phenomenon found in fluid handling systems and processing industries. The components used in such systems and industries experience serious surface damage due to continuous interaction with flowing fluids. Hence, the components fall short to work of its lifetime.

Development of a New Apparatus for the Jet Erosion Test (JET)

2018
The Jet Erosion Test consists of impacting a soil sample with a water jet and analyzing the evolution of the scour depth in order. It was originally designed to assess the resistance of fine soils against overflowing erosion by modelling the headcut migration.

An alternative method for interpreting JET erosion test (JET) data: Part 2. Application

Earth Surface Processes and Landforms, 2017
AbstractThis paper reports the results of jet tester experiments on soil samples of uniform properties which allow quantitative application of the new theory proposed in part 1 of these publications. This theory explores the possibly that a more adequate indicator of soil erodibility may be obtained by using the mass (and so volume) of soil eroded by ...

Slurry Jet Erosion Test Rig: A Review of Erosive Particles Induction Methods and Its Test Parameters

Journal of Bio- and Tribo-Corrosion, 2020
Slurry erosion as problem was identified during World War II in oil and munitions industries. Industrial components were severely damaged due to interaction with fluid and particles inclusion, resulted in huge financial losses. To evaluate the erosion, slurry erosion test set-ups were developed.

Comparison of tunnel and jet methods for cavitation erosion testing

Wear, 1995
Abstract The cavitation erosion behaviour of a number of metals has been studied using a sea water cavitation tunnel test and a fresh water jet cavitation method. Erosion parameters, including erosion rate and depth of damage, have been obtained for both systems and the data shown to correlate with mechanical properties of the metal, such as ...
