1. A Level-set Flamelet Library Model for Premixed Turbulent Combustion
Abstract : 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. READ MORE

2. Development of Transient Flamelet Library Based Combustion Models
Abstract : 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. READ MORE

3. Flamelet modelling of soot formation in diffusion flames
Abstract : In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar diffusion flames than in turbulent ones. READ MORE

4. Simulation of Combustion and Fire-Induced Flows in Enclosures
Abstract : 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. READ MORE

5. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function
Abstract : 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.
