The time-varying lubrication regime is a unique feature of the piston ring-cylinder liner
tribosystem. This study proposes a new method for comparing oil film thickness with critical …

This research paper focuses on evaluating the performance of a Rayleigh step bearing
under thermo-mixed-EHL condition combining the effect of deterministic and stochastic …

As one of the important parameters of bearing operation, temperature is a key metric to
diagnose the state of service of a bearing. However, there are still some shortcomings in the …

In the framework of stochastic representation of surface roughness, a novel Reynolds-type
Equation has been derived recently by the authors and utilized to calculate the average …

The numerical calculation was carried out for the multiscale hydrodynamic step bearing with
ultra-low clearance and nanoscale surface roughness based on the newly developed …

An elastohydrodynamic numerical simulation of a thrust pad bearing with chamfering at inlet
has been studied in this paper. To model the problem, a one-dimensional Reynolds …

Investigating the impact of surface roughness characteristics on three-dimensional journal
bearings while adjusting the eccentricity ratio is the primary goal of this work. Based on …
