Estimation of power input to complex dielectric barrier discharge reactor geometries used in NOx cleaning

PROJECT TITLE :

Estimation of power input to complex dielectric barrier discharge reactor geometries used in NOx cleaning

ABSTRACT:

Studies were carried out to estimate the power input to Dielectric Barrier Discharge (DBD) reactors powered by AC high voltage within the context of their application in nonthermal plasma cleaning of exhaust gases. Power input to the reactors resolve both theoretically and experimentally. Four different reactor geometries energized with 50 Hz and one.5 kHz AC excitation were considered for the study. The theoretically estimated power using Manley???s equation was found to trust the experimental results. Results show that the analytically computed capacitance, while not together with the electrode edge effects, gives sufficiently good results that are matching with the measured values. For complex geometries where analytical calculation of capacitance is often difficult, a novel method of estimating the reactor capacitance, and hence the power input to the reactor, was introduced during this paper. The predicted results were validated with experiments.
