Multi-physics coupling effect on morphology evolution and lubrication characteristics of oil film in hydrostatic thrust bearing [PDF]

AIP Advances
To address the issues of oil film morphology deviation from theoretical design models and lubrication failure in hydrostatic thrust bearings under high-speed and heavy-load conditions caused by temperature rise and structural deformation, this study ...

Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

Materials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

Experimental equipment for measuring physical properties of the annular hydrostatic thrust bearing

EPJ Web of Conferences, 2014
The hydraulic circuit, through which the mineral oil is brought, is an important part of hydrostatic bearings. The annular hydrostatic thrust bearing consists of two sliding plates divided by a layer of mineral oil.

ADAPT: An Autonomous Forklift for Construction Site Operation

Journal of Field Robotics, EarlyView.
ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.
