Characteristics of Capacity Coupled Discharge in Atmospheric Pressure Air

Electrical Characterization of Atmospheric Pressure Gaseous Discharge

This paper reports the generation of atmospheric pressure gaseous discharge and its electrical characterization. For this purpose, a point-plane electrode system has been fabricated. A high voltage power supply (0-11 kV, 50 Hz) was applied across the electrodes. Discharge was generated with and without the dielectric barrier between the electrodes. The gas discharge was seen as in-homogenous fi...

Characteristics of Atmospheric Microplasma in Small Discharge Gaps

Emission spectroscopy analysis and imaging technique were used to study the microplasma phenomena. The microplasma discharge in Ar and N2/Ar was analyzed along the discharge gap area and also for specific periods of time during the discharge. Microplasma showed characteristics specific with an atmospheric glow discharge: positive column, Faraday dark space and negative glow. Spatial and tempora...

Vibrational and rotational CARS measurements of nitrogen in afterglow of streamer discharge in atmospheric pressure fuel/air mixtures

The use of nonequilibrium plasma generated by nanosecond discharges to ignite fuel/air mixtures, known as transient plasma ignition (TPI), has been shown to effectively reduce ignition delay and improve engine performance relative to spark ignition for combustion engines. While this method is potentially useful for many engine applications, at present the underlying physics are poorly understoo...
