SFB/TRR 150: Turbulente, chemisch reagierende Mehrphasenströmungen in Wandnähe


Near Wall Combustion

Turbulente, chemisch reagierende Mehrphasenströmungen in Wandnähe

Cooperative Research Cluster/Transregio 150 associates scientists of Technische Universität Darmstadt (TUD) and the Karlsruhe Institute of Technology (KIT) with the common goal of understanding and explaining processes involved in turbulent, chemically reactive, multi-phase flows near walls.

The behavior of chemical reactions is exceptionally influenced by walls. This is important for various technologically and scientifically significant processes, such as the formation of pollutants in combustion systems, the formation of depositions interfering chemical processes in energy- and process technology or catalytic effects in general. Processes near walls are tremendously affecting new technological concepts, such as the design and development of new combustion engines, after-treatment of exhaust gases, gas turbines, power plants as well as process engineering. Despite their high importance, the underlying mechanisms as well as their mutual interaction are poorly understood.

To improve this situation, the scientists classified the 17 subprojects following three research areas: Research area A: Generic processes and diagnostics, where the underlying processes are studied at simplified, generic targets using newly developed diagnostics; Research area B: Model development and simulation, where the underlying sub-processes are modeled and simulated as well as Research area C: Lead examples, where the sub-models and simulations are studied and evaluated using two complex, technologically relevant applications. These two lead examples are the internal combustion and the successive reduction of NOx using SCR-Catalysts.
