Recent use of ion currents as a sensing strategy in the mechanized oxyfuel cutting processmotivated a series of studies which revealed that the steel work piece contributes second-ary ions in addition to the primary ions classically identified in the oxyfuel flame. In thiswork, we present a computational model that has linked carbon-related chemi-ions as asource of secondary ions in preheating stage of oxyfuel cutting process subject to electricbias voltages. The flames’ response to the electric field at different positive and negativepolarities manifested a better understanding of the physical behavior of current-voltage(i-v) relationship. While copper surface exhibits stable and repeatable i-v characteristics,sporadically enhanced current was observed in positive saturation regime for steel sur-face, and this is believed to be due to the presence of secondary chemi-ions. To thisextent, a source term of gaseous carbon has been assigned to mimic the ‘work surface’reactions. The hypothesis is that since carbon is an important element, it will be diffusingout of the steel surface and evaporate into the flame. [DOI: 10.1115/1.4056845]
