Abstract

The characteristics of roughness of a turbulent flame front in a disc-type combustion chamber were determined with high-speed schlieren photography and image analyzing. The correlations between the characteristics of roughness of the turbulent flame front and the turbulence characteristics or turbulent burning velocity were discussed. The main results are as follows: (1) the RMS value 'a' and integral scale 'Lf' of the flame front roughness are dependent on the turbulence intensity and integral spatial scale, (2) the power spectrum of the flame front roughness is similar to that of turbulent flow, and the microscale of the flame front roughness is close to the Taylor microscale of turbulence.
