One research focus is the characterization of fuel sprays using optical measurement techniques. Microscopic spray parameters (droplet diameter and droplet velocity) are as well a part of the measurement spectrum as the spray analysis as a whole. This serves to determine penetration depths, cone angles and other macroscopic spray parameters. Since fuel injections are fast processes, lasting only a few milliseconds, high-speed measurement techniques with up to 100,000 images per second are increasingly used for the investigation.

The Institute of Engineering Thermodynamics (LTT), founded in 1989, is part of the Department of Chemical and Biological Engineering and employs about 40 staff members. The research focus is the investigation and improvement of processes in energy and process engineering. A key issue is the optimization of combustion processes, spanning from an improved understanding of model flames to experimental studies of complex technical systems (e.g. combustion engines). A closely related field is the study of particle formation, on the one hand to reduce soot emission of practical combustion systems, on the other hand in the synthesis of nanoparticles with defined properties.
