Turbulente, chemisch reagierende Mehrphasenströmungen in Wandnähe

Collaborative Research Centre/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. More

Development of Models and Methods to describe Solid Fuel Combustion in an Oxy Fuel Atmosphere

The safe supply of energy and electrical power will require operation of conventional power plants in the next decades until technical development enables the supply mainly by regenerative sources at minimum emissions of climate gases. More

Droplet Dynamics Under Extreme Ambient Conditions

The fundamental understanding of droplet dynamics is the critical prerequisite to the prediction of natural processes and the optimization of technical systems. Many of these processes happen under extreme ambient conditions – e.g. high pressure or extreme temperatures – and can already be found in technical applications, despite the absence of fundamental knowledge.

Iron has enormous potential to boost the energy transition. The project Clean Circles teams up scientists from multiple disciplines to explore how the metal and its oxides can be used in a cycle as carbon-free chemical energy carrier to store wind and solar power.

Nachhaltige Mobilität mit synthetischen Kraftstoffen

Ziel des Projektes ist es, synthetische Kraftstoffe für Diesel- und Ottomotoren zu entwickeln und zu testen, die nachhaltig produziert und genutzt werden können. Das bedeutet, dass das beim Fahren emittierte CO2 zuvor aus anderen Quellen entnommen wurde, so dass in der Summe wesentlich weniger Treibhausgase durch die Nutzung des Kraftstoffs freigesetzt werden. Dies ist die Hauptmotivation zur Entwicklung der synthetischen Treibstoffe, auch SynFuels genannt.

Cyclic variations in highly optimized spark-ignition engines: experiment and simulation of a multi-scale causal chain

Internal combustion engines, in particular gasoline engines, operate with cyclic variations. Cyclic variability has been observed since the earliest scientific studies on internal combustion engines in terms of the changes in easily measurable operating parameters, such as the maximum cylinder pressure, from one cycle to another. In extreme cases, these variations can lead to misfires or knocking combustions, and in supercharged engines under certain conditions also to so-called mega-knock. Cyclic variations and the resulting unstable combustion are the major limitations for further efficiency improvements in highly optimized gasoline engines. Better understanding and modeling of the underlying physical-chemical processes offer the potential to achieve significant improvements in terms of stability, efficiency and emissions.
