1. Developing Vehicle Configuration Rules
Sammanfattning : 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. LÄS MER
2. Aero Engine Intercooling
Sammanfattning : 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.

3. Efficient Development of Vehicle Configuration Rules
Sammanfattning : 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. LÄS MER
4. On Aero Engine Intercooling
Sammanfattning : 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. LÄS MER
5. Turbocharged HCCI Engine, Improving Efficiency and Operating Range
Sammanfattning : 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. LÄS MER
