A Vortex Model for Wall Flame Height.

Abstract

A two-dimensional vortex model is developed to describe flames on burning walls. The flame is considered a region of intense vorticity generation and is modeled by an equivalent vortex filament. Flame height is predicted by matching the induced air-flow to stoichiometric requirements based on wall mass loss rate or energy release rate. The vortex model predicts the same two-thirds power law relationship that has been determined from other approaches. The quantitative predicted height is within the published limits of experimental certainty.
