  2. 1. Vibrations, damping and power dissipation in Car Tyres

    Author : Martin Fraggstedt; Svante Finnveden; Ines Lopez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Acoustics; Akustik;

    Abstract : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. READ MORE

  4. 2. Modelling the aerodynamics of iron ore pelletizing kilns

    Author : Reine Granström; Christian Fredriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In an iron ore pelletizing plant, crude ore is upgraded to pellets to be used as feedstock in steel-making plants. As part of a grate-kiln pelletizing plant, the rotary kiln is an indurating furnace in which the pellets are sintered. READ MORE

  5. 3. Noise emissions from sustainable transport : A multi-scale modeling approach

    Author : Johan Nygren; Susann Boij; Romain Rumpler; Ciarán J. O'Reilly; Eoin King; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic simulation; sustainable transport; environmental noise; vehicle acoustics; energy efficiency; Trafiksimulering; hållbar transport; samhällsbuller; fordonsakustik; energieffektivitet; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).

  6. 4. Transients in high head Francis turbines

    Author : Chiragkumar Trivedi; Fredrik Engström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : On demand energy market and favourable government policies to encourage the usage of renewable energy have led to a dramatic increase of grid connected wind, solar, and other power in recent years. Penetration of the power above manageable limit, produced using intermittent energy sources, to meet the demand has induced instable grid operations. READ MORE

  7. 5. Receptivity, Stability and Sensitivity analysis of two- and three-dimensional flows

    Author : Guillaume Chauvat; Ardeshir Hanifi; Dan S. Henningson; Ulrich Rist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary-layers; stability; receptivity; sensitivity; transition; mode decomposition; Engineering Mechanics; Teknisk mekanik;

    Abstract : This work deals with various aspects of boundary-layer stability. Modal and non-modal approaches are first used in the study of the global stability of a jet in crossflow. READ MORE
