The aim of the research is to increase the knowledge on combustion processes, with the long-term aim of using this knowledge in order to make the processes more efficient, decreasing the emissions of green-house gases like CO2 and other pollutants like unburnt hydrocarbons, NOx and soot.

The research activities involves development of methods suited for measurement in combustion environments, and to develop and validate theoretical models for these processes. Our measurement methods, which often are based on the use of lasers, are developed from our knowledge in physics and are used to determine the validity of the developed combustion models. The measurement methods are first developed in a laboratory environment with detailed experiments and theoretical knowledge is built to understand how the measurement signal relates to the properties one want to measure. Many of the developed methods are later used to measure in real combustion devices, like gas turbines and internal combustion engines.

The theoretical combustion models are based on chemical kinetics, i.e. identification and characterisation of the numerous chemixal reactions taking place during the combustion process.

The division has for some years also increased activity in areas other than combustion. Among other things, we have a group that works with remote sensing, including the LIDAR technique, a group working toward catalysis and one working towards nanomaterials. In all of these areas the technique development is in focus and research is conducted in collaboration with experts in the respective fields.
