  1. 11. Corrosion of ferritic stainless steels used in solid oxide fuel cells - Investigation of novel coatings in single- and dual-atmosphere conditions

    Författare :Matthieu Tomas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper; Interconnect; Coatings; Alumina; Dual Atmosphere; Area-Specific Resistance; SOFC; Corrosion;

    Sammanfattning : Solid Oxide Fuel Cells (SOFCs) are systems that convert chemical energy into electrical energy. Their high electrical efficiency and clean emissions (when H2 is used as fuel) make them a strong candidate for replacing conventional conversion systems, such as combustion engines. LÄS MER

  3. 12. Dynamic Performance and Design Aspects of Compliant Fluid Film Bearings

    Författare :Matthew Cha; Sergei Glavatskih; Kyung-Woong Kim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant bearing; dynamic performance; design aspects; Machine Design; Maskinkonstruktion;

    Sammanfattning : Due to government regulations together with health and safety reasons, there are increasing demands on reducing hazardous polluting chemicals from fossil fuel power plants. Therefore, more efforts are imposed on using renewable resources such as water, wind, solar and tide to produce clean/green electricity. LÄS MER

  4. 13. Journal bearing design, lubrication and operation for enhanced performance

    Författare :Gregory F Simmons; Rob Dwyer-Joyce; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The increasing introduction of intermittent power sources combined with the de-regulation of electricity markets has led to increased instability in the electrical grid. This has led to increased start-up and shutdown of regulating power sources such as hydro-electric power plants and operation at non-ideal operating states both of which increase the wear and tear on machines.

  5. 14. Sliding bearings for hydropower applications : novel materials, surface texture and EALs

    Författare :Donald McCarthy; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Hydropower, the utilisation of water as a means of driving machinery, has been used for many centuries. Today, the great power of water is being harnessed to generate as much as 20% of worldwide electricity. The requirement for reliable and efficient electricity generation needs to be matched by environmental awareness on the part of the industry. LÄS MER
