  1. 1. Modeling, Control and Optimization of a Plate Reactor

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Staffan Haugwitz; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. READ MORE

    Abstract : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. READ MORE

  4. 4. Physical Modeling and Control of Low Temperature Combustion in Engines

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Anders Widd; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this thesis is model-based control of two combustion engine concepts, Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), using physics-based models. The studied combustion concepts hold promise of reducing the emission levels and fuel consumption of internal combustion engines. READ MORE

  5. 5. High Temperature Tribology of Aluminium Effect of Lubrication and Surface Engineering on Friction and Material Transfer

    University dissertation from Luleå : Luleå University of Technology

    Author : Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.
