Chemical Kinetics Department
Fuel flexibility, reducing pollutant emissions and increasing combustion efficiency, while simultaneously taking aspects of economic viability into account, is one of the greatest challenges in the development of novel combustion technologies. In recent years, modeling and simulation have proved to be excellent new tools for addressing these challenges. Experimental techniques in combination with numerical models are therefore applied rigorously by the Department to predict the reaction kinetics of combustion processes and the formation of pollutants for various gaseous and liquid fuels, and in this way to achieve progress in the optimization of combustion processes.
Gas Turbines Department
The reduction of pollutant and CO
emissions and the successful transfer of the energy system towards renewable energies require the optimization of state-of-the-art power plants and the development of new power plant concepts. Key aspects are the consequent increase of efficiency and operational flexibility and an increased use of biofuels and combined heat and power (CHP) technologies. For these reasons, the Gas Turbines Department focuses its research activities on the investigation, development and implementation of gas turbine-based power plants for a sustainable, decentralized electricity and heat supply.
Numerical Simulation Department
Numerical simulation of the physical and chemical processes in low-emission combustion chambers of aircraft engines or industrial gas turbines requires advanced computation methods. Reliably and accurately predicting pollutant formation, wall heat load, noise emission, as well as the stability and efficiency of combustion are the paramount aims of numerical simulation research.
Combustion Diagnostics Department
Advanced laser-based measurement techniques provide new insights into physicochemical combustion processes. These techniques can visualise flame structures, detect flow relations in the combustion chamber, and can measure how the concentrations of combustion-relevant species are distributed and what temperatures are present.
Chemical Analysis Group
Chemische und instrumentelle Analytik sind in der modernen Verbrennungsforschung ein unverzichtbares Arbeitsgebiet, insbesondere um die Emissionen bei Verbrennungsprozessen detailliert zu analysieren und Maßnahmen für die Schadstoffreduzierung abzuleiten. Während mit Laserdiagnostik reaktive, kurzlebige Spezies wie z. B. OH – Radikale direkt in der Flamme online gemessen werden können, werden durch die instrumentelle und chemische Analytik die mehr oder weniger stabilen Endprodukte der Verbrennung erfasst.
High-pressure Experiments Group
Combustor testing at relevant operation conditions (pressure, temperature, flow field) is still a key in gas turbine combustor development. The “High-pressure Experiments” group is therefore operating the optically accessible high-pressure combustor rig Stuttgart (HBK-S). The research work of the group is focused on fuel flexible gas turbine combustors.
Mass Spectrometry Group
Modern molecular beam mass spectrometry (MBMS) is an optimal instrument for tracing various chemical species in stationary combustion processes. The mass spectrometry group operates two MBMS systems optimized for the investigation of gas-phase reactions and characterization of combustion characteristics of different (alternative) fuels.
