Zero-Dimensional Simulation of Microwave Discharge in Aqueous Ethanol Solution

A microwave discharge inside a bubble filled with microwave plasma in water and ethanol vapors at a pressure of 0.1 atm was simulated in the zero-dimensional approximation. The specific power absorbed by the discharge was used as a parameter. To describe processes in the discharge, reactions with charged particles for water, alcohol, and their decomposition products were added to the set of reactions developed for describing the thermal processes of combustion and detonation. The calculated concentrations of the main decomposition products of an aqueous ethanol solution were consistent with experimental data available in the literature over wide ranges of the feed mixture composition and power inputs to the discharge.

Automated summary

In this study, the effect of microwave discharge on chemical reactions in water and ethanol solutions was investigated through simulation and compared with experimental data. The results demonstrated that the calculated concentrations of the main decomposition products were consistent with the experimental data under different conditions of mixture composition and power inputs.
