1. A Level-set Flamelet Library Model for Premixed Turbulent Combustion
Sammanfattning : The modelling of premixed turbulent combustion has been studied. Premixed turbulent combustion occurs in a range of applications, such as gas turbines and spark-ignition engines. LÄS MER
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. Simulation of Combustion and Fire-Induced Flows in Enclosures
Sammanfattning : Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. 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.

5. Large Eddy Simulation of Turbulent Swirling Flows and Turbulent Premixed Combustion
Sammanfattning : With the increasing concerns about our environment and human health, more and more stringent emission limits have been specified. These adopted and still coming emission limits require and promote more accurate, less experiential methods to design and develop the combustors. LÄS MER
