  1. 21. BlueBellMouse. A Tool for Kinetic Model Development

    University dissertation from Combustion Physics, Lund Institute of Technology

    Author : Raffaella Bellanca; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; combustion; HCCI; reduction; engine; kinetic; simulation; graphical user interface; GUI; optimization; chemical mechanism; Physics; Fysik; Fysicumarkivet A:2004:Bellanca;

    Abstract : The simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. READ MORE

  3. 23. Model Reduction for Control of Stirred Tank Reactor Processes

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Veronica Olesen; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QFT; CSTR; sensitivity functions; Model simplification; closed loop;

    Abstract : Models of chemical processes have a tendency of being far too complex for controller design. In many cases these models are also too complex for simulation together with other sub-systems, due to long simulation times and numerical problems. READ MORE

  4. 24. Modelling Aspects of Wastewater Treatment Processes

    University dissertation from IEA, LTH, Box 118, SE-221 00 Lund, Sweden

    Author : Ulf Jeppsson; Lund University.; Lunds universitet.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

    Abstract : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. READ MORE

  5. 25. Drag reduction using plasma actuators

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Romain Futrzynski; KTH.; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; drag reduction; plasma actuator; DMD; LES; optimization; pulsating flow; strömningskontroll; motståndsminskning; plasma ställdon; DMD; LES; optimering; pulserande flöde; Teknisk mekanik; Engineering Mechanics;

    Abstract : This thesis is motivated by the application of active flow control on the cabin of trucks, thereby providing a new means of drag reduction. Particularly, the work presented strives to identify how plasma actuators can be used to reduce the drag caused by the detachment of the flow around the A-pillars. READ MORE
