Steady state solutions for a lubrication multi-fluid flow [PDF]

open access: yesEuropean Journal of Applied Mathematics, 2011
We describe possible solutions for a stationary flow of two superposed fluids between two close surfaces in relative motion. Physically, this study is within the lubrication framework, in which it is of interest to predict the relative positions of the lubricant and the air in the device.

Effect of functional groups on tribological properties of lubricants and mechanism investigation

open access: yesFriction, 2022
Nine organic compounds were utilized as model lubricants to investigate the impact of functional groups on tribological performances. Nonanoic Acid with carboxyl showed the best lubrication properties, and fluid film and tribofilm were coexistent in its ...

A robust membrane with dual superlyophobicity for solving water-caused lubricant deterioration and water contamination

open access: yesFriction, 2023
Lubricants are often contaminated by water in different ways. Water-polluted lubricants extremely accelerate wear corrosion, leading to the deterioration of lubricity performance.

Time Integration and Steady-State Continuation for 2d Lubrication Equations [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2010
Lubrication equations allow to describe many structurin processes of thin liquid films. We develop and apply numerical tools suitable for their analysis employing a dynamical systems approach. In particular, we present a time integration algorithm based on exponential propagation and an algorithm for steady-state continuation.

Tribological evaluation of environmentally friendly ionic liquids derived from renewable biomaterials

open access: yesFriction, 2017
Unlike most of the conventional ionic liquids (ILs) derived from non-renewable resources, five environmentally friendly ILs ([Ch][AA] ILs) derived from amino acids (AAs) and choline (Ch) were synthesized using biomaterials by a simple, green route: acid ...
