    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; hydropower; sliding wear; sliding friction; self-lubricating; transfer layers; material characterization; surface analysis; high contact pressure; low sliding speed; Machine Elements; Maskinelement;

    Abstract : The ongoing global climate crisis and its impacts calls for urgent actions, such as significant reduction of CO2 emissions by introducing more renewable energy. This has led to a rapid integration of variable power sources, such as wind and solar power, into the electricity systems. READ MORE

  4. 2. Tribology of journal bearings under environmentally adapted lubrication with shaft oscillation

    Author : Jan Ukonsaari; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : To make the hydro power application more environmentally adapted new EALs such as synthetic esters will replace the existing mineral oils. This study aims to exploit the EALs potential in boundary lubrication, especially in slow sliding journal bearings with shaft oscillation as those supporting the Kaplan turbine blades. READ MORE
