A Global PLASIMO Model for H2O Chemistry

Global warming is one of the critical contemporary problems for mankind. Transformation of CO$_2$ into fuels, like CH$_4$, that are transportable with the current infrastructure seems a promising idea to solve this threatening issue. The final aim of this research is to produce CH$_4$ by using microwave plasma in CO$_2$-\H$_2$O mixture and follow-up catalytic processes. In this contribution we present a global model for H$_2$O} chemistry that is based on the PLASIMO plasma modeling toolkit. The time variation of the electron energy and the species’ densities are calculated based on the source and loss terms in plasma due to chemical reactions. The short simulation times of such models allow an efficient assessment and chemical reduction of the H$_2$O chemistry, which is required for full spatially resolved simulations.
