Optical Diagnosis of Pulsed Streamer Discharge under Atmospheric Pressure
نویسندگان
چکیده
This paper introduces recent optical measurements of radicals in atmospheric pressure non-thermal plasma. Laser-induced fluorescence (LIF), laser absorption, and optical emission spectroscopy (OES) techniques have been applied for density and temperature measurements of OH radicals, NO molecules, ozone, atomic oxygen, atomic nitrogen, and N2( A3Σ u ) metastables in pulsed corona and pulsed dielectric barrier discharges under atmospheric pressure. These radical measurements are indispensable to develop an efficient non-thermal plasma reactor for decomposing atmospheric pollutants because radicals play important roles in the decomposition processes of pollutants. Keywords—Nonthermal plasma, Laser-induced fluorescence, Laser absorption, Radical

Improved performance of a barrier-discharge plasma jet biased by a direct-current voltage
One of the challenges that plasma research encounters is how to generate a large-scale plasma plume at atmospheric pressure. Through utilizing a third electrode biased by a direct-current voltage, a longer plasma plume is generated by a plasma jet in dielectric barrier discharge configurations. Results indicate that the plume length increases until it reaches the third electrode with increasing...
متن کاملElectric field determination in streamer discharges in air at atmospheric pressure
The electric field in streamer discharges in air can be easily determined by the ratio of luminous intensities emitted by N2(C 3 u) and N2(B 2 + u ) if the steady-state assumption of the emitting states is fully justified. At ground pressure, the steady-state condition is not fulfilled and it is demonstrated that its direct use to determine the local and instantaneous peak electric field in the...
متن کاملDiagnostics of Dielectric Barrier Discharge at Atmospheric Pressure by Laser Spectroscopic Measurements
Spatial distribution of electron density inside parallel plate dielectric barrier discharge (DBD) is discussed in this presentation by using CO2-laser heterodyne interferometry measurement. This interferometry measurement has been used for low pressure plasmas and applied to DC microplasmas at atmospheric pressure recently. To derive the electron density inside pulsed plasmas like DBD, we used ...
متن کاملExperimental and numerical study of the propagation of a discharge in a capillary tube in air at atmospheric pressure
This paper presents an experimental and numerical study of a pulsed air plasma discharge at atmospheric pressure propagating in a capillary glass tube. In this work, we have compared the discharge structures and the axial propagation velocities of discharges. First, we have studied a needle-to-plane configuration without tube. For applied voltages in the range 7 − 18 kV, we have observed in exp...
