A Detailed Two-Dimensional Numerical Study of Spark Ignition Including Ionization

Numerical study on the spark ignition characteristics of a methane–air mixture using detailed chemical kinetics

“…The minimum ignition delay time occurred at / = 0.9. These ignition delay times were obtained using the same ignition energy density (q = 120 GW/m 3 side for the methane-air mixture. This has been demonstrated by many experiments (Fig.…”

“…On the other hand, numerical simulation is a convenient method for studying the specific effects of any factor on spark ignition characteristics and for calculating important physical and chemical data such as instantaneous high temperature and heat release rate, which are impossible to obtain experimentally. Other factors, such as natural convection, heat transfer by radiation, and ionic species can be ignored because they have little effect on the flame kernel formation and flame propagation [2,3]. The effects of the ignition source geometry on the ignition processes and ignition reaction pathway have already been studied [4].…”

Ignition of CNG Mixtures in Spark Ignition Engines

“…E bd represents the breakdown energy to produce the plasma kernel. After a forming of the plasma between the electrodes the heat source of the mixture medium can be calculated directly from the electrical current in the secondary coil circuit I, which changes during time [8]:…”

Numerical study on the spark ignition characteristics of hydrogen–air mixture using detailed chemical kinetics

“…Kono et al [9] investigated the mechanism of flame kernel formation produced by shortduration sparks using a set of partial differential equations with unsteady and two-dimensional cylindrical coordinates. Thiele et al [10] investigated the early development of a stable flame kernel during spark ignition based on a detailed model for coupling two-dimensional cylindrical reactive flows with electrodynamics.…”
