  1. 16. Neutron Irradiation Techniques

    Författare :Julius Scherzinger; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinide Be; fast-neutrons; NE-213 liquid scintillator; He-4 scintillators; pulse-shape discrimination; Cf-252; absolute detection efficiency; neutron irradiation; Fysicumarkivet A:2016:Scherzinger;

    Sammanfattning : The He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. LÄS MER

  3. 17. Aerothermal Experimental Investigation of LPT-OGVs

    Författare :Borja Rojo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental; Turbine Rear Structure; Aerodynamics; Wind Tunnel; CFD; Gas Turbine; Engine Exit Structure; Outlet Guide Vane; Heat transfer.; Turbine Exhaust Case; Turbine Rear Frame; Exit Guide Vane;

    Sammanfattning : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. LÄS MER

  4. 18. On the hydrodynamic lubrication in tilting pad thrust bearings

    Författare :Sergei B. Glavatskikh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : The primarily objective of this work was to investigate the performance of environmentally adapted synthetic oils in the hydrodynamic lubrication regime. A special test facility has been designed and manufactured for this purpose. The facility contains two equalising tilting pad thrust bearings typical of design in general use. LÄS MER

  5. 19. An Experimental Study to Measure And Improve the Grout Penetrability

    Författare :Ali Nejad Ghafar; Stefan Larsson; Almir Draganovic; Ulf Erik Lindblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Penetrability; Filtration; Erosion; Cement-based grout; Grout spread; Grout penetrability measurement; Dynamic grouting; Instantaneous variable pressure; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : An essential demand in any underground facility is to seal it against the water ingress to reduce the time and cost of the construction and the corresponding environmental hazards. To achieve this, obtaining sufficient grout spread is of great importance. LÄS MER

  7. 20. Charged current quasi-elastic muon neutrino interactions in the Baby MIND detector

    Författare :Sven-Patrik Hallsjö; Soler Paul; UK University of Glasgow College of Science and Engineering School of Physics and Astronomy; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The T2K long-baseline neutrino experiment in Japan is designed to study neutrino oscillations, to determine the mixing angles and mass-squared difference of the neutrino mass eigenstates and, potentially, to discover CP violation in neutrinos by comparing neutrino to antineutrino oscillations. In the near detector complex 280 m downstream of the produc- tion target at the Japanese Particle Accelerator Research Centre (J-PARC), the WAGASCI experiment will measure the ratio of cross sections from neutrinos interacting with a water and scintillator targets, in order to constrain neutrino cross sections essential for the T2K neutrino oscillation measurements.
