  2. 1. Industrial Induction Heating - with a focus on multi coil solutions

    Author : Kenneth Frogner; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction heating; travelling wave; industrial heating; multi coil; TWIH; SM2C;

    Abstract : Most types of materials and components use heating during the manufacturing process, with a large potential for cost and energy savings. Induction heating is the most energy efficient industrial heating technology for many applications, but so far technical limitations has delayed large scale introduction. READ MORE

  5. 3. Lean Homogeneous combustion for SI-Engines

    Author : Gerben Doornbos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lean homogeneous combustion; lean limit.; Dual Coil Ignition; ammonia formation catalyst; valve-timing;

    Abstract : This thesis is about the application of lean homogeneous combustion in SI engines using a passive SCR after treatment system. By implementing this concept a decrease in fuel consumption and engine out NOx is expected. The data and results are obtained through engine experiments. READ MORE

  6. 4. On the Design of Ultra-fast Electro-Mechanical Actuators

    Author : Ara Bissal; Göran Engdahl; Torbjörn Lembke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electro-mechanical drive; Circuit breakers; HVDC transmission; Eddy currents; Finite element; Electromagnetic; Thermal; Mechanical; Coils; Armature; Image motion analysis.;

    Abstract : The continuously increasing demand for connecting electric grids with remote renewable energy sources such as wind power and photovoltaic cells has rekindled interest in high voltage direct current (HVDC) multi-terminal networks. Although HVDC networks have numerous benefits, their adoption relies entirely on the availability of HVDC circuit breakers which, compared to traditional alternating current circuit breakers, have to operate in a time frame of milliseconds.
