Abstract: The effect of thermal expansion on the minimum energy of gas spark ignition is studied using a mathematical model of spark ignition. It is shown that the thermodiffusion model of gas spark ignition underestimates the minimum spark energy by more than a factor of two. The dependence of the minimum spark ignition energy on the Damköhler number is studied, which characterizes the ratio of the flame propagation velocity to the speed of sound in a gas.

Keywords: fuel gas, spark, thermal expansion, minimum spark energy.
