Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The chapter delves into the impact of surface textures on the tribological performance of lubricated concentrated point contacts. It discusses how specific micro-geometries, such as dimples, bumps, grooves, and ridges, can enhance lubricant spreading and film thickness, thereby reducing friction and wear. The study employs numerical methods to analyze the performance of different textures, including micro-cylindrical, micro-elliptical prisms, and micro-rectangular prisms, under various operating conditions. The results indicate that elliptical prism textures with the major axis perpendicular to the rolling direction show the most significant improvements in film thickness and coefficient of friction reduction. This chapter offers valuable insights into the design and optimization of surface textures for enhanced tribological performance in applications such as rolling bearings, piston rings, and gears.
