Three-Dimensional Recomposition of the Absorption Field Inside a Non-Buoyant Sooting Diffusion Flame

Abstract

A remote scanning retrieval method was developed to investigate the soot layer produced by a laminar diffusion flame established over a flat plate burner in microgravity. Experiments were conducted during parabolic flights. This original application of an inverse problem leads to the three-dimensional re-composition by layers of the absorption field inside the flame. This technique provides a well defined flame length that substitutes other subjective definitions associated with emissions.
