Abstract

Increasing demands on emission limitations caused by legislative directives call for numerical simulation to support the development of automotive exhaust gas aftertreatment systems. Since the efficiency in pollution abatement of automotive converters decreases over the technical lifetime, the aging behavior has to be considered when designing aftertreatment systems. The objective of this work is a better understanding of thermal aging of diesel oxidation catalysts and NOx trap catalysts.

Abstract

Subject of this work was the experimental investigation of an confined, lifted, non-premixed swirl flame by employing a novel airblast nozzle. For the time-resolved determination of all three velocity components, a measurement campaign was carried out using a commercial 3-D LDA system. Concentration and temperature measurements in the reacting field were also performed to better understand the complex turbulent and chemical interactions.
