Characteristics of operating mode in a rotating arc and optimization of chemical process by control of the mode

Summary form only given. In a typical gliding arc reactor, the arc string expands two dimensionally. Compared to the gliding arc, rotating arc reactor can expand arc string three dimensionally by rotating flow of reactant within reactor resulting in volumetric highly thermal environment favorable for the chemical reaction such as thermal decomposition or oxidation process. The expansion of arc not only enlarges chemically active volume but also enhances efficiency of power usage by arc for the process. High efficiency of power usage is due to the fact that the rotating arc can sustain expanded state of arc with rotating movement without repetitive expansion process from short arc to longer arc.
