The behavior of turbulent premixed flame was investigated by using a small ion gap in a closed vessel. Considering that ionization is strongly related to the combustion reaction, the analysis of ion-current wave yields the characteristics of turbulent flame structure. The main results are as follows: (1) The time scale of the ion current obtained in turbulent flame decreases with an increase in turbulence intensity. (2) The length scale of the ion current is nearly constant within the range of turbulence intensity in this experiment. (3) The fluctuation of the flame front produced by the turbulence is observed by analyzing the ion-current wave, and the change in the fluctuation versus the turbulence intensity is similar to the change in the roughness of turbulent flame front observed with flame photography.
