“…Much of the previous work on simulating ignition has idealized the problem and treated one-dimensional spherical and cylindrical spark kernels. Several authors have used two-dimensional simulations of spark discharge in a non-reactive gas [4][5][6][7] to investigate the fluid mechanics involved in the spark ignition process, and two-dimensional simulations of ignition are discussed in [8][9][10][11][12][13][14][15][16]. In all the two-dimensional studies, the classic toroidal shape of the hot gas kernel is observed, which occurs due to fluid flow inward toward the gap center.…”

“…Akram [5] and Thiele et al [10] performed simulations for several electrode geometries, however, the geometries were limited to blunt and cone-shaped electrodes with diameters of 1 to 2 mm. Most recently, Han et al simulated ignition in methane-air [14] and hydrogen-air [15] mixtures and studied the effects of temperature, electrode gap distance, electrode size (cylindrical electrodes), and spark duration on the predicted minimum ignition energy (MIE). These studies used detailed chemistry and provided new insight on the effect of different spark parameters on ignition.…”

“…The method was validated either by comparing the resulted parameters with those reported in literature [21][22][23][24][25][26][27][28], or by analysing also the time evolution of emitted radiation within the same time interval [29].…”

“…where _ m is the burner mass flow rate, subscript q denotes quenching, and A is the coefficient of proportionality between L st and _ m. Quantity L q is the minimum separation between parallel walls for which a flame can propagate [22][23][24]. Quenching diameters in round tubes are typically 50% larger [25].…”
