  1. 6. Towards Automation of Non-Destructive Testing of Welds

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Patrik Broberg; Högskolan Väst.; Luleå tekniska universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell arbetsvetenskap; Industrial engineering; Welding; non-destructive testing; NDT; Experimentell mekanik; Experimental Mechanics;

    Abstract : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

    Abstract : Train transportation is a vital part of the transportation system of today anddue to its safe and environmental friendly concept it will be even more impor-tant in the future. The speeds of trains have increased continuously and withhigher speeds the aerodynamic effects become even more important. READ MORE

  3. 8. Phase change, surface tension and turbulence in real fluids

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Daniel Albernaz; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Sprays are extensively used in industry, especially for fuels in internal combustion and gas turbine engines. An optimal fuel/air mixture prior to combustion is desired for these applications, leading to greater efficiency and minimal levels of emissions. READ MORE

  4. 9. Suspensions of finite-size rigid spheres in different flow cases

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Walter Fornari; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Dispersed multiphase flows occur in many biological, engineering and geophysical applications such asfluidized beds, soot particle dispersion and pyroclastic flows. Understanding the behavior of suspensionsis a very difficult task. READ MORE

  5. 10. Scenarios of drop deformation and breakup in sprays

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Tímea Kékesi; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Sprays are used in a wide range of engineering applications, in the food and pharmaceutical industry in order to produce certain materials in the desired powder-form, or in internal combustion engines where liquid fuel is injected and atomized in order to obtain the required air/fuel mixture. The optimization of such processes requires the detailed understanding of the breakup of liquid structures. READ MORE
