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

    Author : Sofia Larsson; Lisa Prahl Wittberg; Luleå tekniska universitet; []
    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.

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

    Author : Berhanu Mulu; Sebastian Muntean; Luleå tekniska universitet; []
    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

  5. 3. A study of turbulence and scalar mixing in a wall-jet using direct numerical simulation

    Author : Daniel Ahlman; Arne V. Johansson; Lars-Erik Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningmekanik; Fluid mechanics; Strömningsmekanik;

    Abstract : Direct numerical simulation is used to study the dynamics and mixing in a turbulent plane wall-jet. The investigation is undertaken in order to extend the knowledge base of the influence of the wall on turbulent dynamics and mixing. The mixing statistics produced can also be used to evaluate and develop models for mixing and combustion. READ MORE

  6. 4. Hydraulic Power Steering System Design in Road Vehicles : Analysis, Testing and Enhanced Functionality

    Author : Marcus Rösth; Jan-Ove Palmberg; Nick Vaughan; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Power Steering; Active Safety; Comfort function; Shuttering; Linear modelling; Fluid mechanics; Strömningsmekanik;

    Abstract : Demands for including more functions such as haptic guiding in power steering systems in road vehicles have increased with requirements on new active safety and comfort systems. Active safety systems, which have been proven to have a positive effect on overall vehicle safety, refer to systems that give the driver assistance in more and less critical situations to avoid accidents.

  7. 5. Numerical Modeling of Flows Related to Gas Turbine Combustors

    Author : Robert-Zoltán Szász; Strömningsteknik; []
    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
