Parallel-plate nitrogen dielectric barrier discharge (DBD) driven by a quasi-pulsed power source (60 kHz) is simulated using a fully-implicit 1D self-consistent fluid modeling code Simulated discharged currents of gap distances (0 5 07 and 1 0 mm) agree very well with measured data while simulated discharged currents of wider gap distance (1 2 mm) fail to reproduce the measured data It is found that the discharge mode is homogeneous Townsend-like for the former case while it is filamentary-like for the latter case based on the experimental observation These findings demonstrate that previous numerical studies showing mode transition by changing the gap distance may require further investigation (C) 2010 Elsevier B V All rights reserved
