Two-surface slip in EHL contacts: influence on film thickness and friction
Rayan Ajeeb, Marko Polajnar, Mitjan Kalin

Oznake: interakcije trdno-tekoče;elastohidrodinamično mazanje;pogoji zdrsa;koeficient trenja;optimizacija debeline filma;fluid–solid interaction;elastohydrodynamic lubrication;slip conditions;coefficient of friction;film thickness optimisation;
This work examines symmetric shear-limited slip at the two fluid–solid interfaces in a fully flooded, isothermal elastohydrodynamic line contact using a fully coupled Navier–Stokes and elastic deformation framework. This formulation computes the velocity field and wall shear rate directly, allowing ...

ǂThe ǂmechanism and the parameters influencing friction and film thickness for single-surface boundary slip in thermal EHL contacts
Rayan Ajeeb, Tomaž Požar, Mitjan Kalin
Izvirni znanstveni članek
Oznake: modeliranje;elastohidrodinamično mazanje;drsenje;trenje;debelina filma;modelling;elastohydrodynamic lubrication (EHL);slip;friction;film thickness;
This study presents a new and fundamental mechanism together with the parameters that affect elastohydrodynamic lubrication (EHL) boundary slip using Navier–Stokes formulations and implementing the shear-limited slip model proposed by Spikes and Granick, which captures the onset and evolution of the ...

Decoupling the effects of shear thinning and thermal softening on EHL film thickness and friction
Rayan Ajeeb, Marko Polajnar, Mitjan Kalin

Oznake: elastohydrodynamic lubrication;shear thinning;thermal softening;coefficient of friction;film thickness;Navier–Stokes modelling;
In elastohydrodynamic lubrication (EHL) contacts, lubricant viscosity plays an important role in friction and film formation. Previous studies have established that shear thinning and thermal softening influence both friction and film thickness. However, the distinct effects of temperature- and shea ...
