Flow Field of a Bunsen Flame according to Source Sheet Approximation

Abstract

A volume source sheet plus a uniform flow is used to represent the flow field of a two‐dimensional Bunsen flame when the density ratio of the unburned to burned gases is 5.5. The unknown flame shape is determined by the requirement that the velocity normal and relative to it, i.e., the local flame speed is constant. The flow field is computed by the method of squares and compares favorably with that obtained experimentally.
