Research Area C:

Lead examples

In research area C the mutual interaction of the underlying mechanisms is investigated both experimentally and numerically, using scientifically and technically highly relevant lead examples.

Lead example 1: Internal combustion engines

The influence of walls (e.g. cylinder, piston) on the combustion of fuel within engines is investigated. Also, the effects of fuel or lubricant-films at the walls on the combustion are tackled.

Lead example 2: Exhaust gas system

The second lead example is the evaporation of urea water solution within the exhaust gas system of IC engines, as it is important for selective catalytic reduction of NOx. The solution is sprayed on the hot surface of the exhaust gas pipe and hereby decomposed into ammonia. Ammonia is reacting with the NOx leading to harmless substances.

Research area C is investigating the effect of hot walls on the decomposition of the urea-water solution. Therefore, the newly developed measurement techniques of research area A as well as the isolated models of research area B are needed for the investigation of both lead examples.
