  1. 1. Analysis of the cold flow field in a rotary kiln

    Author : Sofia Larsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The pelletizing process where the crude ore from the mine is upgraded to pellets is a process which includes several stages involving complex fluid dynamics. In this thesis, focus is on the grate-kiln pelletizing process and especially on the rotary kiln, with the objective to get a deeper understanding of the aerodynamics and its influence on the combustion process.

  2. 2. An experimental and numerical investigation of a Kaplan turbine model

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Berhanu Mulu; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Hydropower is a renewable, reliable and highly efficient source of energy. Hydropower has the ability to run as a base load and to adjust load rapidly. This makes hydropower suitable for coupling with other renewable energy sources to stabilize frequency fluctuations. READ MORE

  3. 3. Numerical Modeling of Flows Related to Gas Turbine Combustors

    University dissertation from Department of Heat and Power Engineering, Lund university

    Author : Robert-Zoltán Szász; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; Gases; vortex breakdown; swirl; CFD; gas turbine;

    Abstract : The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. READ MORE

  4. 4. Solar wind interaction with the terrestrial magnetopause

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars-Göran Westerberg; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Magnetic reconnection plays an important role in the transfer of mass, energy and momentum from the solar wind to the terrestrial magnetosphere. The earliest contributions to the theory of magnetic reconnection dates from the beginning of the 1930's. READ MORE

  5. 5. Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars

    University dissertation from Luleå : Luleå tekniska universitet
