  1. 1. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    Author : Jari Hyvönen; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Variable Compression Ratio; Homogeneous Charge Compression Ignition VCR; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; Cylinder-to-cylinder; Turbocharging; Multi cylinder; Cylinder balancing; Thermal Management; HCCI;

    Abstract : The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. READ MORE

  2. 2. On Surface Topography of Cylinder Liners

    Author : Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  3. 3. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

    Abstract : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. READ MORE

  4. 4. Residual stress in a T-butt joint weld : cylinder versus plane plate geometry

    Author : Berth Eriksson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Hållfasthetslära; Solid Mechanics;

    Abstract : The welding process introduces residual stress originating from the heating, melting and cooling of the material. From the point of view of fatigue and stress corrosion cracking, the weld residual stress perpendicular to the weld axis is of particular interest. READ MORE

  5. 5. Cylindrical Waveguide Slot Antenna Analysis

    Author : Johan Wettergren; Chalmers University of Technology; []
    Keywords : basis function; mutual admittance; cylinder; MPIE; slot; integral equation; waveguide; antenna; mutual coupling; moment method; EFIE;

    Abstract : Waveguide slot antennas with longitudinal and transverse slots are analyzed using a rigorous method. The antennas are divided into regions, which are analyzed separately and matched by a moment method procedure. At the apertures between the regions, the electric fields are expanded in trigonometric basis functions. READ MORE
