Plasma Assisted Ignition at High Pressures and Low Temperatures. PAI Kinetics and Fast Gas Heating

摘要

This is the final report for this three year effort with the most important results presented herein. These are: (i) experiments and modeling of the fast gas heating at low (3 9 mbar) pressures at high reduced electric fields E/N = 200-400 and specific deposited energy up to 0.1 eV/molecule in synthetic air; (ii) experiments and modeling of the fast gas heating at moderate (up to 60 mbar) pressures at high electric fields and specific deposited energy more than 1 eV/molecule leading to dissociation degree up to 100%; (iii) experiments on measurements of a density of metastable N2 molecules in the afterglow of the pulsed nanosecond discharge by technique of a cavity ring down spectroscopy; (iv) experiments on electric field measurements in nanosecond high voltage surface dielectric barrier discharge in air together with analysis of the combustion initiation by this type of discharge in C2H6:O2 stoichiometric mixture at P = 1 atm.
