Gliding Arc Reactor under AC Pulsed Mode Operation: Spatial Performance Profile for NOx Synthesis

“…This may involve the study of temperature and density differences between the plasma channel and surrounding gas, which could be complex. However, several studies have been conducted to study the arc motion contributed by buoyant force under normal or hypergravity conditions. , Further study with implementation of the approaches in those studies could be beneficial.…”

“…However, several studies have been conducted to study the arc motion contributed by buoyant force under normal or hypergravity conditions. 37,38 Further study with implementation of the approaches in those studies could be beneficial. Higher concentration of both NO and NO 2 in the outlet gas stream was observed in the cases with a higher duty cycle, as shown in Figure 3a.…”

Rotating Gliding Arc: Innovative Source for VOC Remediation

“…6. The plasma channel is periodically reignited between the points of connection, similar to classic horn electrode design [13]. However, in RGA design there is no need to introduce the additional gas flow through the narrow nozzle of gas input to force the arc to glide along the electrodes.…”

Effect of actuating voltage and discharge gap on plasma assisted detonation initiation process

“…In view of its merits including fast response, wide frequency band, flexible arrangement, etc, some researchers are trying to improve the performance of engines such as scramjet, detonation engines, and internal engines by the PAC technology [1][2][3][4][5]. Among the known discharge methods for plasma generation, such as spark discharge, microwave discharge, gliding arc, etc [6][7][8], dielectric barrier discharge (DBD) is widely used for combustion control as it is capable of effectively preventing arc formation, operating in a wide pressure range, and has a low heat loss [9][10][11][12][13][14].…”
