PIV Study on Steady and Periodic-Pulsed Dielectric-Barrier-Discharges
The flows induced by different modes of plasma discharge over a 20 conical forefody are studied with a two-dimensional particle image velocimetry in a still air chamber with one atmosphere pressure. The effects of pulse duty ratio on the induced maximum crossflow velocity and maximum axial vorticity are compared with those of steady discharge. Effects of pulse frequency and ac voltage are discu...
متن کاملDevelopment of a Lumped Element Circuit Model for Approximation of Nanosecond Pulsed Dielectric Barrier Discharges
This work presents a circuit model for calculating the total energy dissipated into neutral species for nanosecond pulsed direct current (DC) dielectric barrier discharge (DBD) plasmas. Based on experimental observations, it is assumed that the nanosecond pulsed DBD’s which have been proposed for aerodynamic flow control can be approximated by two independent regions of homogeneous electric fie...

متن کاملAtmospheric pressure plasma of dielectric barrier discharges*
The dielectric barrier discharge (DBD) has a number of industrial applications and has been a subject of research for many years. Many studies have been carried out to understand the underlying DBD physics. Despite the fact that much progress has been made, some important issues are still far from being clear. In this work, we summarize the basics of DBD physics and introduce innovative concept...
متن کاملMultiple microdischarge dynamics in dielectric barrier discharges
Dielectric barrier discharges ~DBDs! are pulsed atmospheric pressure devices in which the plasma forms as an array of microdischarges having diameters expanding from 10 to 100’s mm and area densities of 10 to 100’s cm. The microdischarges are ,10’s ns in duration and are terminated by charging of the dielectric barrier which removes voltage from the gap. If microdischarges are spaced sufficient...
