  2. 1. Developing Vehicle Configuration Rules

    Author : Anna Tidstam; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; usability tests; design automation; visualization tools; product data management; configuration; vehicle configuration rules; PDM;

    Abstract : Vehicles are sold in many variants with different engine horsepower, wheel dimensions, type of headlights etc. Vehicle customers specify individual vehicles by the selection of such features during the so-called “sales configuration” process. READ MORE

  4. 2. Aero Engine Intercooling

    Author : Xin Zhao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PIV; CFD; porous media; aero engine; pressure measurements; intercooling control; system performance; intercooler; variable flow path;

    Abstract : Intercooling has the potential to provide a shortcut to the next generation aero engines with higher bypass ratio (BPR), higher overall pressure ratio (OPR) and higher turbine inlet temperature (TIT) by lowering the high pressure compressor (HPC) delivery temperature. To be able to establish a systematic understanding of aero engine intercooling, the heat transfer and pressure loss characteristics of a given intercooler architecture need to be known in the parameter range anticipated for the engine optimization.

  5. 3. Efficient Development of Vehicle Configuration Rules

    Author : Anna Tidstam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process modeling.; development process; matrix-based visualization; vehicle configuration; configuration rules; information modelling;

    Abstract : The aim of this PhD thesis is to describe an efficient and user-friendly development process for vehicle configuration rules. The development of vehicle configuration rules precedes the sales configuration, and is the process of authoring, evaluating and releasing configuration rules sets. READ MORE

  6. 4. On Aero Engine Intercooling

    Author : Xin Zhao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aero engine; CFD; porous media; coolant flow control; system performance; intercooler;

    Abstract : Establishing an optimal intercooled aero engine constitutes a coupled problem where the conceptual design of the intercooler and the engine has to be considered simultaneously. The heat transfer and pressure loss characteristics will depend on the choice of the intercooler architecture. READ MORE

  7. 5. Turbocharged HCCI Engine, Improving Efficiency and Operating Range

    Author : Thomas Johansson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; NVO; turbo; direct injection; combustion; CAI; low temperature; simulation; engine;

    Abstract : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. READ MORE
