and
the Rk region where the bending occurs corresponded well to the region where the smallest scale of flame
wrinkling measured as a fractal inner-cutoff approaches the characteristic flame instability scale and
becomes almost constant. A power law of ST/SL with (P/P0)(u0
/SL) was clearly seen when ST was determined
using Æcæ = 0.1 contours, and the exponent was close to 0.4, indicating agreement with the previous
results using the mean flame cone method and the significant pressure effects on turbulent burning
velocity.
