1. On the Computation of Turbulent Mixing Processes with Application to EGR in IC-engines
Abstract : This thesis deals with turbulent mixing processes occuring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. READ MORE

2. Reduced models for flows in IC-engines
Abstract : The finite response time of the turbocharger is the most notable effect of transient operation on a turbocharged diesel engine. To fulfill future emission requirements, high amounts of transient EGR will be required even though after-treatment devices are being used. READ MORE

3. Indirect measurements for control and diagnostics of IC engines
Abstract : The combustion process in internal combustion engines determines engine power, fuel consumption, exhaust emissions and combustion noise. Measurement and analysis of in-cylinder pressure plays an important role in the improvement and optimization of engine performance. READ MORE

4. CFD of Duct Acoustics for Turbocharger Applications
Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. In this work the main focus is the turbocharger compressor and a discussion of turbocharger acoustics and earlier work within the area is presented, giving an insight into its sound generating mechanisms and the damping effect it has on pressure pulses, i.

5. Flow Duct Acoustics : An LES Approach
Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. Simulations are an important tool for enhanced understanding; they give insight into the flow-acoustic interaction in components where it is difficult to perform measurements. READ MORE
