1. Modeling of Diesel Fuel Spray Formation and Combustion in OpenFOAM
Abstract : The formation, ignition, and combustion of fuel sprays are highly complex processes and the available models have various shortcomings. The development and application of multidimensional CFD models, that describe the different phenomena have rapidly increased through the use of commercial and public software (e.g. READ MORE

2. Small Orifices - Diesel Combustion and Spray Investigations
Abstract : Future demands on diesel engines, such as the need to meet stricter emission legislation, improve performance and lower fuel consumption, for lowering transportation cost and carbon dioxide emissions, forces the development of engines to take a major step in the near time. During the years of engine development, all components have been optimised in small steps at a time, but larger steps must now be taken to meet requirements of the future. READ MORE

3. Development of Transient Flamelet Library Based Combustion Models
Abstract : Three different methods for Reynolds-averaged Navier-Stokes computational fluid dynamics modeling of non-premixed ignition and combustion using tabulated chemistry have been developed. All methods make use of flamelet libraries, where the flamelet auto-ignition process is parameterized using a progress variable. READ MORE

4. Modeling of Spray Formation and Development in OpenFOAM with Application to Diesel and Alcohol Fuels
Abstract : Legislation with reagards to fuel emissions are becoming more stringent. This creates a need for improved engine concepts and fuels. This work is part of an ongoin project to create a concept for a direct injection dual fuel engine, which uses alcohol as main fuel and diesel as a pilot. READ MORE

5. High Repetition Rate Laser Diagnostics for Combustion Applications
Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE
