A mathematical function that simulates the injection of the thermal transfer in gas is proposed. The simulated discharge is of a negative point to plane mass type, with an interelectrode distance of 12 mm and a symmetry about the axis of discharge. The spatial and temporal evolution of neutrals is analyzed based upon the equations of continuity, momentum and energy in a cylindrical geometry. For the geometry of the system, the FCT （flux corrected transport） procedure was adopted.展开更多
