Modeling and simulation of electronic excitation in oxygen-helium discharges and plasma-assisted combustion

Abstract

The present work concerns the generation of electronically excited oxidizers in non-thermal discharges in the context of plasma-assisted hydrogen and methane combustion at atmospheric pressures. These conditions are of practical relevance for the combustion technology. However, as the conversion of electrical power into particular, chosen chemical degrees of freedom is facilitated by low molecular interaction, the atmospheric parameter range is often neglected in the literature. This work provides the design and validation of accurate and efficient computational models for several experiments in this parameter range.
