  2. 16. Stochastic Reactor Models for Engine Simulations

    Author : Martin Tunér; Förbränningsmotorer; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SRM; Stochastic Reactor Model; Engine Simulation; Chemical kinetics; HCCI; Direct injection; Combustion; NVO; Modeling; PDF;

    Abstract : The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. READ MORE

  4. 17. Conceptual design of hydraulic systems for automotive engine applications : simulation, optimisation and testing

    Author : Jochen Pohl; Nicola Nervegna; Linköpings universitet; []
    Keywords : ;

    Abstract : The main contribution of this thesis lies in the area of systems design, and especially of such systems that involve several engineering domains, so-called multidomain or heterogeneous systems. The design of these systems is concerned with a need for efficient tools, especially in the early conceptual phase of the development process. READ MORE

  5. 18. 1D engine simulation of a turbocharged SI engine with CFD computation on components

    Author : Ulrica Renberg; Hans-Erik Ångström; Laszlo Fuchs; Per Birkestad; KTH; []
    Keywords : 1D modeling; CFD modeling; turbine efficiency; pipe flow; turbocharged engine; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Techniques that can increase the SI- engine efficiency while keeping the emissions very low is to reduce the engine displacement volume combined with a charging system. Advanced systems are needed for an effective boosting of the engine and today 1D engine simulation tools are often used for their optimization. READ MORE

  6. 19. Development of Methods for Analysis and Optimization of Complex Jet Engine Systems

    Author : Tomas Grönstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; optimal control; variable cycle engine; performance analysis; double bypass variable cycle engine; jet engine; BDF methods; selective bleed variable cycle engine; turbofan; ODAE;

    Abstract : This thesis describes the development of GESTPAN (GEneral Stationary and Transient Propulsion ANalysis), a generalized system for the design, steady-state and transient simulation of gas turbine systems. Some of the main achievements in the thesis are related to the development of new algorithms or integration of existing numerics tailored to simplify the structure and use of generalized gas turbine simulation systems.

  7. 20. Optical Diagnostics for Engine Efficiency in Gasoline Compression Ignition

    Author : Miao Zhang; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Optical engine; Engine Eciency; Multiple-injection strategies; Thermodynamic analysis;

    Abstract : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. READ MORE
