Examining the cascade hypothesis for turbulent premixed combustion

The cascade hypothesis, which was introduced in application for premixed co mbustion by Yakhot (1988) and Sivashinsky (1988), is examined against the c orrelations of the turbulent burning velocity data by Bradley, Lau and Lawe s (1992) (BLL data). A new, less restrictive formulation of the cascade hyp othesis is suggested. The formulation is shown to be consistent with the BL L data. Various flame characteristics- fractal dimensions, inner cutoffs, m ain asymptotic regimes - are determined form the BLL data on the basis of t he cascade hypothesis.
