Abstract

Abstract: A self-consistent state-to-state model of pure hydrogen has been used to investigate the development of nanosecond repetitively pulsed discharges and dielectric barrier discharges, the latter coupling the kinetic model with an equation for the circuit, thus mimicking an insulated electrode with an external capacitance. Vibrationally excited states play a fundamental role, affecting the degrees of dissociation and ionization, as well as internal and free-electron distributions.
