  1. 21. An Experimental and Numerical Study of the Heat Flow in the Blast Furnace Hearth

    Författare :Maria Swartling; Pär Jönsson; Henrik Saxén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast furnace; hearth; heat transfer; model; experimental; numerical; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : This study has focused on determining the heat flows in a production blast furnace hearth. This part of the blast furnace is exposed to high temperatures. In order to increase the campaign length of the lining an improved knowledge of heat flows are necessary. Thus, it has been studied both experimentally and numerically by heat transfer modeling.

  3. 22. Shape measurements using temporal phase unwrapping

    Författare :Lars Kinell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This licentiate thesis is devoted to shape measurements using two different optical methods. The first one is a classical triangulation method, which uses projected fringes. The second one is a new interferometric method, which uses wavelength scanning. Both are whole field measuring methods. LÄS MER

  5. 24. Optical Measurements of Rolling Friction Coefficients

    Författare :Yiling Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. LÄS MER

  7. 25. Solar Shading for Low Energy Use and Daylight Quality in Offices: Simulations, Measurements and Design Tools

    Författare :Marie-Claude Dubois; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; screens; venetian blinds; awnings; design tools; measurements; computer simulations; solar-protective glass; heating; cooling; visual comfort; daylighting; energy use; Shading devices; solar protection; Architecture; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Sammanfattning : This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance.
