Focusing on basic lubrication problems this book offers specific engineering applications The book introduces methods and programs for the most important lubrication problems and their solutions. It is divided into four parts. The first part is about the genera·solving methods of the Reynolds equation， including solutions of Reynolds equations with different conditions and their discrete forms， such as a steady-state incompressible slider， journa·bearing， dynamic bearing， gas bearing and grease Iubrication. The second part gives the 'energy equation solution'. The third part introduces methods and programs for elasto-hydrodynamic lurbication， which links the Reynolds equation with the elastic deformation equation. The fina·part presents application lubrication programs used in engineering. ·Provides numerica·solution methodologies including appropriate sofiware for the hydrodynamic and elasto-hydrodynamic lubrication of bearings ·Offers a clear introduction and orientation to al·major engineering lubrication problems and their solutions ·Presents numerica·programs for specific applications in engineering， with specia·topics including grease-lubricated bearings and gas bearings ·Equips those working in tribology and those new to the topic with the fundamenta·tools of calculation 　With an emphasis on clear explanations the text offers a thorough understanding of the numerica·calculation of lubrication for 'jraduate students on tribology and engineering mechanics courses. with more detailed materials suitable for engineers This is an accessible reference for senior undergraduate students of tribology and researchers in thin-filrn fluid mechanics.
