Cavitation and film formation in hydrodynamically lubricated parallel sliders

D Bulut, N Bader, G Poll - Tribology International, 2021 - Elsevier
Cavitation influences the pressure distribution in hydrodynamically lubricated contacts and
therefore also the load carrying capacity. Film formation in parallel sliders is investigated …

The effect of fluid viscoelasticity in lubricated contacts in the presence of cavitation

SS Gamaniel, D Dini, L Biancofiore - Tribology International, 2021 - Elsevier
In this work we study the influence of fluid viscoelasticity on the performance of lubricated
contacts in the presence of cavitation. Several studies of viscoelastic lubricants have been …

A new approach for modeling viscoelastic thin film lubrication

H Ahmed, L Biancofiore - Journal of Non-Newtonian Fluid Mechanics, 2021 - Elsevier
Lubricants can exhibit significant viscoelastic effects due to the addition of high molecular
weight polymers. The overall behavior of the mixture is vastly different from a simpler …

A modified viscosity approach for shear thinning lubricants

H Ahmed, L Biancofiore - Physics of Fluids, 2022 - pubs.aip.org
Lubrication is essential to minimize wear and friction between contacting surfaces in relative
motion. Oil based lubricants are often enhanced via polymer additives to minimize self …

Optimization design for slip/no-slip configuration of hydrophobic sliding bearings using Monte Carlo search

surface for improving tribological performance of the sliding bearing, such as load carrying …

[PDF][PDF] A study of cavitation effect in a journal bearing using CFD: A case study of engine oil, palm oil and water

Z Rasep, M Yazid, S Samion - Jurnal Tribologi, 2021 - researchgate.net
Cavitation occurs when the flow reaches a divergent zone in the journal bearing
(Tauviqirrahman et al., 2017). As the liquid enters a different zone, cavitation occurs, the …

Cavitation over solid surfaces: microbubble collapse, shock waves, and elastic response

D Abbondanza, M Gallo, CM Casciola - Meccanica, 2023 - Springer
We discuss the interaction of the strongly nonlinear fluid motion induced by the collapse of a
vapor microbubble over a planar surface and the elastic dynamics of the underlying solid …
