NSF-DFG Confine: Plasma-Catalysis in Confined Spaces for Cold Start NOx Abatement in Automotive Exhaust

The Confine project is aimed to investigate the influence of short-lived species generated by discharges in small volumes on the coupling of plasma and catalytic processes. Due to the complex chemistry in gas mixtures intended a plug flow model was established which includes the volume and surface reactions, the electron energy balance and the heat equation. In a first step a mixture of helium and water was investigated and validated by LIF measurements of OH number density by project partners at the University of Minnesota.
