Simulations with COMSOL Multiphysics were performed, in order to analyze the gas flow patterns during the induced ignition of gases. Simplified calculations were performed. The ignition spark was assumed to have a temperature of 2000 K and a laminar flow was selected.
2D calculations were performed, as to reduce computing times. The distance between the electrodes was considered as parameter and varied between 10 to 40 mm.
