Modelling NOx-Formation in Combustion Processes

Abstract
As the regulations of pollutant emission is getting more and more strict, models of pollutant formation, as a part of system level models for control design, are needed. In this thesis NOx (nitrogen oxides) formation is modeled. A method is developed to mix equilibrium and non-equilibrium reaction equations to model NOx formation in combustion processes. This algorithm reduces high-index DAE systems by introducing ``reaction invariants''. Two models are built with help of this algorithm which describe NOx formation during combustion in a cylinder in a spark ignition car engine and in a gas turbine (for more information about the combustion models see [4] and [7]). The models use both equilibrium and non-equilibrium/dynamical reaction... (More)
