Tribological properties of real foods using extended Stribeck curves and their relationship with nutritional and rheological parameters

Journal of Texture Studies, Volume 55, Issue 4, August 2024.
Tribological properties of 19 commercial food products in 6 categories (yogurts, dressings, spreads, porridges, emulsified sauces, and syrups) were investigated. The extended Stribeck curves across the four frictional regimes (the static, boundary, mixed, and hydrodynamic regimes) varied depending on the flow behavior, nutritional compositions, and the

Large‐Scale Numerical Simulation of the Solid Lubricant Behavior in the Leg Joints of Insects

Advanced Theory and Simulations, Volume 7, Issue 6, June 2024.
Semi‐solid lubricant in the insect legs joints is represented by cylindrical fragments with a diameter of ≈1 µm. The results of numerical simulation show that the fragments tend to adhesion and the formation of clumps of different shapes and sizes. Such a system allows maintaining clearance between surfaces while reducing friction and elimination of ...

Tribological Performance of Laser‐Based Surface Textured Nonconformal Contacts

Advances in Tribology, Volume 2024, Issue 1, 2024.
The benefits of surface textures on rolling and sliding tribological contacts have been an exciting field of study over the last three decades. Laser surface texturing (LST) is a comparatively newer texturing methodology that yields repeatable precise microtextures.

A Review on the Impact of Bio‐Additives on Tribological Behavior of Diesel Fuels

Advances in Tribology, Volume 2024, Issue 1, 2024.
Automobile engines require lubrication to lessen the impact of friction due to the high levels of wear and frictional heat generated by the sliding parts. Wear and friction will cause engine parts to endure for less time, be less reliable, and require more maintenance. Diesel fuel can potentially be replaced with biodiesel among other fuels.

Performance Analysis of Thermal and Surface Roughness Effect of Slider Bearings with Unsteady Fluid Film Lubricant Using Finite Element Method

Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.
The streamline upwind Petrov‐Galerkin (SUPG) finite element method was used in this study to investigate the thermal and surface roughness effects on an inclined slider bearing with an unsteady fluid film. One‐dimensional transverse and longitudinal surface roughness models were considered with the supposition that roughness is stochastic and has a ...
