1. LES modelling of spray combustion
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

2. Combustion Simulations with reduced mechanisms using hybrid optimization
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikAbstract : In order to simulate complex combustion systems, the kinetic mechanisms describing the chemical processes have to be reduced. To minimize the error introduced by the reduction, coefficients of the reaction rates included in the mechanisms can be adjusted in ways so that simulations using the reduced mechanism behave like simulations that use detailed mechanisms.

3. Laminar Burning Velocity of Ethanol, Acetaldehyde and Ethanol-Acetaldehyde Flames
University essay from Lunds universitet/Fysiska institutionenAbstract : The objective of this study is to get new experimental data regarding to the burning velocities of ethanol, acetaldehyde and their mixture which has been performed by the heat flux method. It is known that the heat flux method for determination of laminar burning velocities is an efficient technique since the burning velocity can be determined directly, without applying extrapolations.

4. Optimization of Global Reaction Mechanisms Evaluated on The Sandia Flame D
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : The main goal is to develop and evaluate global reaction mechanisms. The optimization is done using two methods; Laminar Flame Speed and Perfectly Stirred Reactor. READ MORE

5. Combustion Characteristics of MCV/LCV Fuels - A Numerical Chemical Kinetics Study at Gas Turbine Conditions
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The purpose of this Master’s Thesis is to develop a model for numerical simulations in order to kinetically characterize different Medium Calorific- Low Calorific Value (MCV-LCV) fuel gas mixtures. Adding fuel components with a very low heating value or inert species affect the stability of the standard gas turbine combustor design. READ MORE
