  1. 1. Numerical investigation on the effects of out-of-flatness on leakage in metal-to-metal seals

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

    Author : Lumi Canhasi; [2017]
    Keywords : ;

    Abstract : Since the usage of pressurized systems, there has been a challenge to prevent and control leakage of different fluids. When a metal-to-metal face seal is designed, different aspects are to be considered. Its ring shaped sealing surface is designed to prevent leakage and also to maintain pressure. READ MORE

  2. 2. Reflection, absorption and filtering of ground vibrations, A study in the use of different arrays of cylinders to attenuate and filter ground vibrations

    University essay from Chalmers tekniska högskola/Institutionen för bygg- och miljöteknik

    Author : Alexander Sandercock; [2017]
    Keywords : Vibrations; reflection; absorption; ground; acoustics; dynamics; rayleigh; waves;

    Abstract : With the increased rate of urbanization comes an increase in disturbing ground vibrations. These can be produced by building operations, different kinds of traffic and in some cases mining and military operations. It is therefore necessary to try and reduce the amplitude of these disturbing, and in extreme cases damaging vibrations. READ MORE

  3. 3. Analysis of Multicomponent Data to Study Esker Structures, Turku-Finland

    University essay from Uppsala universitet/Geofysik

    Author : Julia Fridlund; [2017]
    Keywords : Finland; esker structures; reflection seismology; multicomponent data; S-wave; Finland; rullstensås; reflexionsseismik; flerkomponentdata; S-vågor;

    Abstract : Eskers are long winding ridges that originate from gravel that has travelled in meltwater streams in glaciers. At the study site, Virttaankangas plane in southwest Finland, there are esker structures covered by sediments. One reason why it is important to study eskers is because they are used for purifying drinking water. READ MORE

  4. 4. Developing a Mounting Tool for Magnetic Poles in the Stator of a new Wave Power Generator : Mounting Tool for Magnets

    University essay from KTH/Industriell ekologi; KTH/Industriell ekologi

    Author : Alexander Isakson; Simon Lundgren; [2017]
    Keywords : ;

    Abstract : At KTH Royal Institute of Technology, a novel type of transverse flux generator aimed for ocean wave energy conversion is being developed. This machine is complex to assemble, and the aim of this project was to develop a tool to aidin mounting neodymium magnets, fixed in rows, next to each otherto create a single magnetic pole.

  5. 5. Offshore Floating Platforms : Analysis of a solution for motion mitigation

    University essay from KTH/Bro- och stålbyggnad

    Author : Alberto Rodriguez Marijuan; [2017]
    Keywords : Offshore Wind; floating platform; wave tank test; hydrodynamic pressure; structural; hydrodynamic load; heave plate.;

    Abstract : Recent events regarding energy policies throughout the globe and advances in technology are making offshore wind farms become a reality. Most offshore wind farms are still, however, built close to land masses, and need to be rigidly attached to the seabed in one way or another. READ MORE
