1. Laser Sheet Imaging and Image Analysis for Combustion Research
Abstract : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

2. Spray and Spray Combustion Characteristics of Diesel-Ethanol Fuel Blends
Abstract : In Diesel engines, the quality of fuel atomization and fuel-air mixing inside the cylinder have important effects on the combustion process, and therefore strongly related to the fuel efficiency and emission formation. To understand how the injected fuel mixes with air and combustion processes in a Diesel engine, fundamental spray experiments can be carried out in a constant chamber under different engine-like conditions.

3. 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

4. Numerical Modelling of Diesel Spray Injection, Turbulence Interaction and Combustion
Abstract : This thesis covers two main topics. The first is numerical modelling ofcavitating diesel injector flows, focusing on describing suchflows using asingle-phase cavitation model based on a barotropic equation of statetogetherwith a homogenous equilibrium assumption. READ MORE

5. 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
