“…Friction coefficient and the Stribeck curve predicted by this model agree well with experiments. More attentions in recent years have been paid to the effect of artificial surface microstructure called the texture, which could be beneficial to the load carryingcapability if properly designed [601], so efforts have been made to find optimum shape, size, and distribution of micro dimples [602], and a mixed structure combining the texture with wall-slip domain has been investigated, too, as will be discussed in next section.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…(2) The hydrodynamic pressure is obtained by solving the equation ( 8) with the boundary conditions ( 14), ( 18), (19), based on the finite difference method (FDM) and the successive over relaxation (SOR) method. More information about the FDM can be found in Li et al's 52 work. The asperity contact pressure is achieved by solving the equations ( 20)-( 22).…”

The thermal effect of friction plays an important role in friction pairs working under heavy load and starved lubrication conditions, such as the piston ring and cylinder liner (PRCL) system of two-stroke marine diesel engines. Friction heat will degrade the lubrication and increase the scuffing risk. In this study, considering the thermal effect of friction, the tribological characteristics of the top ring and cylinder liner of a two-stroke marine diesel engine under starved lubrication are studied. It is found that the temperature rise due to friction is significant and has a strong influence on the tribological characteristics of the PRCL system. Moreover, based on the orthogonal test method, the effects of groove textures under different oil supplies are also explored. Only well-designed groove textures can reduce friction and wear at the same time.

In modern internal combustion engines, the lubricant viscosity affects greatly the friction power loss. To obtain maximum fuel economy of the engines, the lubricants with different viscosities are considered to evaluate the friction properties of the compression ring-cylinder liner conjunction in the engines in this study. To conduct the evaluation, an improved mixed lubrication model is developed with considerations of the cylinder liner deformation, the lubricant thermal effect & transportation, and the change of lubrication condition from full flooded to starve. On this basis, the influence of different viscosity lubricants on the minimum oil film thickness, friction, power loss, FMEP, and wear load are investigated. The numerical result indicates that the low viscosity lubricant is more beneficial to facilitate the change of lubrication condition from starve to fully flooded. Furthermore, the low viscosity lubricant will result in large wear load on the compression ring surface while reducing the friction power loss.
