Abstract

The paper presents experimental study of nanosecond surface dielectric barrier dis- charge (nSDBD) in air and application of nSDBD for initiation of the two-stage ignition of n-heptane in mixture with air. The emission spectroscopy study of rotational and vibra- tional structure of 2+ system of N2 molecules has been performed for a classical air flow control SDBD configuration. The energy deposition into the discharge has been measured. Strongly non-equilibrium distribution of rotational population is observed in the spectra at the leading and trailing edges of the high-voltage pulse. The time resolved spatial distri- bution of the rotational temperature along the dielectric surface has been measured. The second part of the paper concerns the ignition of stoichiometric mixture of C7H16/O2/N2 with nanosecond SDBD in Rapid Compression Machine (RCM). Different regimes of igni- tion initiated by discharge are discussed, including cool flame and fast ignition.
