Abstract
[Soot resulting from combustion processes is known to have a negative impact on health and environment. Soot also may lead to material damages especially in gas turbines. Therefore, a deeper insight in the processes leading to the formation and consumption of the soot precursors and soot particles is needed. For describing these processes a reaction kinetical model is needed representing the different steps. The processes happening in the gas phase are described by elementary chemical reactions, whereas for the particle phase a more complex formalism is needed due to the enormous number of different particles possible. In this work the processes in the particle phase are represented by the detailed soot model. A kinetical description of the processes is developed along with a mathematical representation of the model. This is done for shock tube conditions that can be assumed to be spatially homogeneous, allowing to focus on models of the chemical processes. In a next step this model is implemented for laminar flame conditions. Here additional transport phenomena are considered which helps improving gas phase and particle reaction models for representing soot formation in practical combustion devices. Besides giving a deeper insight into soot formation processes, the detailed soot model is needed for calibrating and adjusting a simplified soot model. This is used for simulating soot formation in complex technical systems like gas turbines.]
