Mathematical Model of Piston Ring Sealing in Combustion Engine
Polish Maritime Research, 2015 This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as ...

THE EFFECT OF SOLID FILM FORMATION ON OIL DISPLACEMENT [PDF]
Proceedings of SPE Production Research Symposium, 1962 Abstract Many crude oils contain components which lead to the formation of solid films at the interface between the crude oil and water. Film forming ability varies widely among crude oils. It is completely absent in some, although most crudes will exhibit film formation at oil-water interfaces ...

Stability characteristics of lubricating film in mill oil-film bearings [PDF]
, 2018 Purpose The stability characteristics of an oil film directly influence the safety and service life of mill oil-film bearings. However, very limited work has been done to address the stability characteristics of mill oil-film bearings. To this end, this

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Advanced Functional Materials, EarlyView.Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
