This study focuses on the characteristics of turbulent flame structures in V-shape turbulent premixed flames to evaluate the turbulent combustion dynamics of fractal turbulence generator. The details of the non-reactive turbulent flow characteristics with the fractal turbulence plate were explained in the previous study of Part I. In this work, the integral length scale of non-reactive flow was additionally investigated to obtain a Borghi-Peters diagram. By comparing the Borghi-Peters diagram shown as a result of the non-reactive flow with the reaction OH-PLIF image, it was confirmed that the flame characteristics for each regime were well represented. Also, the irregular turbulence of premixed flame was quantitatively analyzed using the flame brush obtained by the mean progress variable method. As a result, the flame brush of the fractal turbulence generator was wider than the perforated plate and mesh type. Finally, it was found that the thickness and angle of the flame brush were proportional to the turbulence intensity and turbulent Reynolds number, which are dimensionless numbers of turbulent flow.
