  1. 16. Characterization of black corrosion in reinforced concrete structures: analyses of field samples from southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jenny Halling; [2019]
    Keywords : black rust; anaerobic corrosion; reinforced concrete; corrosion products; green rust; microbial corrosion; Earth and Environmental Sciences;

    Abstract : I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. READ MORE

  3. 17. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Ahmed Azeez; [2018]
    Keywords : ;

    Abstract : In the transition from conventional to green energy production resources, steam turbines are used to satisfy the lack of energy during peaks in the demand times and the limited access of renewable resources. This type of usage for steam turbines makes them operate on a flexible schedule, which leads to unpredictable issues related to shorter component life and faster crack propagation. READ MORE

  4. 18. A parametric study of oil-jet lubrication in gear wheels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Dona Biju; [2018]
    Keywords : Jet lubrication; velocity ratio; inlet size; heat transfer;

    Abstract : A parametric study of oil-jet lubrication in gear wheels is conducted using Computational Fluid Dynamics (CFD) to study the effect of the different design parameters on the cooling performance in a gearbox. Flow in oil jet lubrication is found to be complex with the formation of oil ligaments and droplets. Various hole radii of 1.5, 2 and 2. READ MORE

  5. 19. Effect of Surface roughness for Hydro Turbine Step-up Efficiency

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ermias Beraki; [2018]
    Keywords : Hydropower; Surface roughness; Hydro Turbine; Step-up Efficiency; IEC 62097 standard; Prototype and Model;

    Abstract : The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. READ MORE
