  1. 1. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  3. 2. System Simulation of Electric Driveline and Active Suspension using Simcenter Amesim

    University essay from Umeå universitet/Institutionen för fysik

    Author : Simon Lundberg; [2022]
    Keywords : System Simulation; Mechatronics; Amesim; Electric driveline; Active suspension;

    Abstract : Computer simulation software’s are arguably some of the most convenient and utilized tools for an engineer as it lets them model real phenomena and observe different operations without having to perform the operation physically, thus saving both time and resources. Naturally these tools varies in design depending on their intended area of application and while a large number of them supports modeling of more than one physical domain, it is often cumbersome to attain a functional interaction between them.

  4. 3. Simulation Testbed of a Combustion Engine in Simulink for Control Purposes

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Erik Bolin; [2019]
    Keywords : Technology and Engineering;

    Abstract : Control theory plays a big part in the development of more efficient and environ- mental friendly combustion engines. But the process of designing good controllers can be very time consuming and complex. One way to reduce the time spent on design and testing of a controller is to use simulations to get fast feedback of the controllers performance. READ MORE

  5. 4. Stochastic Knock Control for Improved Efficiency

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonas Vedin; Robert Widén; [2019]
    Keywords : Knock control; Stochastic knock control; Knock simulation;

    Abstract : Increasing the efficiency and performance of internal combustion engines is always of interest in the automotive industry. One limiting factor to achieve this in gasoline combustion engines is the ignition timing which can not always be set where optimal ignition efficiency and performance is obtained. READ MORE

  6. 5. Investigation of Mode Superposition as Modelling Approach for Crankshaft Torsion

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jonas Johansson; [2018]
    Keywords : Torsion; Crankshaft; Modal analysis; Mode superposition;

    Abstract : With tougher emission standards for heavy duty trucks, good control of the engine is of importance. By taking into consideration the torsional vibrations occurring in the crankshaft, the engine control can be improved. READ MORE
