Large‐Eddy Simulation of Oil‐Water Annular Flow in Eccentric Vertical Pipes
Chemical Engineering & Technology, 2020AbstractOne of the difficulties related to oil exploration is transporting heavy oil since its high viscosity causes high‐pressure drop and energy consumption. In order to save energy, the core annular flow (CAF) can be applied where a two‐phase annular flow occurs, with peripheral water flowing offering a reduction in energy expenditure.

Online condition monitoring of large synchronous generator under eccentricity fault
2017 12th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2017Condition monitoring of large synchronous generators plays a critical role in power generation systems. It prevents unexpected failure of the systems. About half of the failures in synchronous generators are related to eccentricity fault. This paper presents a comprehensive review of various eccentricity fault diagnosis methods employed over the last ...

The measure method for eccentricity of large aperture aspheric mirror
AOPC 2019: Space Optics, Telescopes, and Instrumentation, 2019Due to the large size of large-aperture aspheric mirrors and the long optical path each of them needs to inspect, the deviation of the optical axis from the structural reference cannot be accurately measured by conventional inspection means. However, as the aperture of the optical lens increases, alignment puts higher requirements on the concentricity ...

Circular Base Plates with a Gap under Large Eccentric Load
Mechanics of Advanced Materials and Structures, 2013Circular base plates are commonly used for cylindrical columns, such as pylons in cabled-stayed bridges, lighting poles, electric power line posts, and even buildings. In some structures and conditions, a little gap is considered between the base plate and foundation. In this case, the whole forces are transmitted to the foundation via bolts. There are

Unbalanced Inertia Forces in Slider-Crank Mechanisms of Large Eccentricity
Journal of Applied Mechanics, 1958Abstract An analysis of the various harmonic orders of the inertia forces in offset slider-crank mechanisms is presented. The formulas given here are valid for all practical values of eccentricity ratio (ratio of offset to length of connecting rod) and crank to connecting rod ratio.

Particle Flow Simulation for Large Diameter Squat Silos Eccentric Discharge
Applied Mechanics and Materials, 2011The scale model of squat silo in large diameter was established with Particle Flow Code (PFC3D) in this paper. This scale model uses the centrifuge model test principle for reference and provides the field of gravity in the calculation of archetypal squat silo.
