1. Studies of Gas Turbines Combustion Chambers: Use of New Fuels and Development of New Tools
Sammanfattning : The growing world electricity demand and environmental concerns pushes toward new technology for electricity production. Within the thermal processes for electricity production, two axis of research are being developed to meet the needs of the industry, namely using renewable fuels and new generation burners technology.

2. Development of Transient Flamelet Library Based Combustion Models
Sammanfattning : 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. LÄS MER
3. Modelling of methane and hydrogen enriched methane flames in industrial gas turbine burners
Sammanfattning : 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. LÄS MER
4. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function
Sammanfattning : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.
