Stability Models for Augmentor Design Tools and Technology Assessment
Abstract
The objective of the project was to design and study new flame stabilizers for augmentor systems that could lead to improved static flame stability. The project consisted of (a) development of new augmentor flame holder designs and their experimental characterization; and (b) demonstration of numerical predictions of the flame behavior using the resulting experimental designs and measurements. Four flame configurations were considered in the both experiments and computations: partially premixed flame in high temperature vitiated flow and in room temperature air flow, fully premixed flame and hybrid of fully-partially premixed flame. All studies demonstrated improved static flame stability of the new flame holder. Computations results, which used Damkorhler number similarity, compared well generally with those from experiments. However, simulations showed that flames remain attached to the bluff body, and formed on the edge of the body wake; but these features were not observed in experiments.
