1. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities
Abstract : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion. READ MORE

2. Application of Laser Techniques in Combustion Environments of Relevance for Gas Turbine Studies
Abstract : In the work presented in this thesis, different laser-based techniques were employed for measurements in different combustion devices. Laser-based techniques enable non-intrusive and in-situ measurements to be carried out, in which high spatial and temporal resolution can be obtained. READ MORE

3. Modelling effects of flame development on stationary and oscillating premixed turbulent combustion
Abstract : The vast majority of contemporary models of premixed turbulent flames applied to multi-dimensional RANS numerical simulations of combustion in gas turbine engines and aero-engine afterburners focus on fully-developed flames, characterized by fully-developed turbulent diffusivity, thickness, and burning velocity. However, abundant experimental data obtained from statistically stationary premixed flames clearly show that a typical turbulent flame develops as it is convected by mean flow from a stabilization zone.

4. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners
Abstract : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. READ MORE

5. Modelling of methane and hydrogen enriched methane flames in industrial gas turbine burners
Abstract : The majority of the power production in the world today is based on combustion of coal, oil and natural gas. Most countries have agreed that the amount of CO2 emitted to the atmosphere will have to be decreased to keep the global warming at sustainable levels. READ MORE
