This paper analyzes the near-field acoustic characteristics of premixed wrinkled, flame fronts subjected to acoustic excitation. The flame thickness is assumed to be very small compared to the length scale of the acoustic oscillations. Thus the flame is treated as a finite temperature discontinuity. The values of acoustic pressure and velocity on the wrinkled flame surface are transferred to a mean reference surface by means of a Taylor's expansion. A Boundary Integral Equation describing the expectation value of the coherent acoustic pressure field in the domain of interest is derived. The flame surface wrinkling is modeled by a Weierstrass-Mandelbrot fractal function. Numerical results for a dump combustor configuration using the Boundary Element Method(BEM) are presented. The acoustic pressure field is seen to be highly two-dimensional in the case of the wrinkled flame. The flame surface impedance is seen to decrease with increase in excitation frequency. The difference between the acoustic pressure on the flame surface and the wall is shown to be significant in the case of a wrinkled flame subjected to acoustic excitation from the downstream. The transmitted acoustic field characteristics due to upstream excitation are seen to have a weak dependence on wrinkling. The normalized flame surface acoustic impedance is found to vary monotonically from the base of the flame to the tip of the flame in the case of smooth flames (i.e flame front with no wrinkling). The wrinkled flame however, is seen to have a nearly constant impedance variation along its surface. © 2003 by Santosh H and R. I. Sujith.
