Modeling of piston ring wear [PDF]
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2020 A theoretical study of piston ring wear in large two-stroke engines is presented. Piston rings in combustion engines are manufactured with an initially defined shape of the surface contacting the cylinder liner. Further the ring surface working against the cylinder liner is coated with layers of ceramic materials to accommodate the running-in process.

Tribological behavior of co-textured cylinder liner-piston ring during running-in
Friction, 2021 The running-in of cylinder liner-piston rings (CLPRs) is the most important process that must be performed before a marine diesel engine can be operated. The quality of running-in directly affects the reliability of a CLPR.

Investigation of Wear Pattern in Piston Ring of an IC Engine
Tribology in Industry, 2019 Piston Ring, as small as it appears, plays quite an important role in contribution to friction and wear in an IC engine. As a first approximation most wear models, have quantified wear of a piston ring in terms of total wear volume, total weight loss or ...

Advanced Energy Materials, Volume 13, Issue 2, January 13, 2023., 2023 Using in situ X‐ray tomography, the phase transformation and microstructural evolution of a copper sulfide cathode in solid‐state batteries is 3D visualized and characterized. Copper inclusions generate after phase transformation and the electrode cracks have a strong preferential orientation within the x‐y plane of the cell.

Estimating the non-dimensional energy of vortex rings by modelling their roll-up [PDF]
, 2021 The non-dimensional energy of starting vortex rings typically converges to values around 0.33 when they are created by a cylinder piston or a bluff body translating at a constant speed. To explore the limits of the universality of this value and to analyse the variations that occur outside of those limits, we present an alternative approach to the slug-
