Our results contribute to the development of efficient, low-emission energy converters or to reduce deposits in energy technology or chemical engineering, for example.

When walls and chemistry interact
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.
These various scientific topics give rise to the overall objectives of the TRR 150, represented by the following three main research areas:
Video: TRR 150 in 3 minutes
In this video, TRR 150 spokesperson Prof. Dr. Andreas Dreizler summarizes the motivation and research questions of the Collaborative Research Center. The interaction of chemical reactions with transport processes (turbulence and diffusion) in the presence of a wall is being investigated. The aim is to gain a better understanding of the processes and, based on this, to develop mathematical models. These will then be integrated into overall models to demonstrate this predictive capability using appropriate systemic considerations.

B: Model developement and simulation
We develop and validate sub-models and high-resolution numerical simulations using experimental insights and data from A. The focus is on individual processes for future electrofuels as well as higher near-wall pressures and temperatures. From this, overall models for the interaction of chemical reactions, turbulent flow, multiphase processes and wall heat transfer are being developed.

C: Lead examples
The new models and methods are applied to technically relevant processes and are critically evaluated. The focus is on internal combustion – including the electrofuels dimethyl carbonate and methyl formate – as well as reactive multi-phase flows in the exhaust train of IC engines.

“In science you use your creativity and imagination all the time”
The Center of Excellence in Combustion celebrates the International Day of Women and Girls in Science
In order to achieve full and equal access to and participation in science for women and girls, and further achieve gender equality and the empowerment of women and girls, the United Nations General Assembly declared 11 February as the International Day of Women and Girls in Science in 2015. The Center of Excellence in Combustion celebrates this event and releases a video with statements from two of its most inspiring women researchers.
