Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

The Structural Optimum of Hydrostatic Thrust Bearings to Avoid Cavitation

Lubricants
Cavitation of oil film is harmful for all kinds of hydrostatic bearings, so the method to avoid cavitation in hydrostatic thrust bearings by optimizing the structure of bearings is proposed in this study. Based on the pressure distribution expressions of

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.

UNIVERSAL STAND FOR STUDYING SEALING AND BEARING UNITS OF COMPRESSOR MACHINES [PDF]

Avtomobilʹnyj Transport (Harʹkov), 2018
The proposed stand is designed to test sealing and bearing units of various types, because these units, regardless of their type, require almost the same auxiliary stand systems, as well as practically the same measurement system.

Turbulent Shear Flow in Hydrostatic Thrust Bearings

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1980
This paper is concerned with the effects of a turbulent flow in hydrostatic thrust bearings. Applying an equation representing the "low of wall" to the three-dimensional turbulent shear flow, the local velocity distributions between a rotating disk and a fixed wall are calculated as a function of Reynolds number, local pressure gradient and the ratio ...
