“…The simplicity of its electric circuitry and adaptability to an AC glow-arc discharge are some of the most attractive features of this method. Modular plasma discharge working in an array has been already reported by Kuo and Koretzky [58,59]. Fig.…”

“…Usually, an arc discharge has a very small volume. However, introducing a gas flow between the electrodes, such as in the operation of a plasma torch [17], [18], can greatly enlarge the discharge volume. The gas flow increases the length of the arc and impedes the establishment of a fixed anode hot spot.…”

The high-voltage discharge and plasma plume generated by the torch module are described in a quiescent environment and in a supersonic crossflow. Voltage-current characteristics of the discharge and optical images of the plasma plume are used to characterize the operation of the torch module. The principal advantages of this torch module are its compact design, durability, and operational flexibility. The torch module can be operated in periodic or pulsed modes, depending on the power supply used. In the periodic mode presented in this paper, the capacitors are charged at the line frequency of 60 Hz resulting in a cyclical discharge at a frequency of 120 Hz. In this mode, peak and average powers reaching 8 and 2. REPORT DATE (DD-MM-YYYY) IS. SUBJECT TERMS

“…The frame of a surface gap spark plug, which has a concentric electrode pair, is used in the construction of a plasma torch module. The construction procedure and components of the module have been described in detail in the previous work, 13 from which a U.S. patent 15 has been awarded. In the following, only the new additions of the modified torch module are described.…”
