Water-Lubricated Journal Bearings: Marine Applications, Design, and Operational Problems and Solutions provides cutting-edge design solutions, common problems and methods for avoiding them, and material selection considerations for the use of water-lubricated journal bearings in marine environments. These bearings have many advantages, including the absence of the potential for oil contamination. They are also sensitive, and their production processes can be challenging, but this book outlines techniques and concepts designed to overcome these challenges, emphasizing their role in durable and reliable propulsion systems in modern, safe, and environment-friendly shipping. Propeller shafts, water-lubricated stern tube bearings, problems frequently encountered with water-lubricated propeller shaft bearings and sliding bearings alongside solutions to these problems are all covered, as are the hydrodynamic properties of water-lubricated bearings, operation at low revolution speeds, high-speed bearings, hybrid bearings, and more. Foundational concepts of tribology related to friction, lubrication, wear, and fluid/solid and solid/solid interactions in ship stern tube and water-lubricated turbine machinery are also discussed.
