Adam Langman and Gus Nathan from the CET recently published a paper in Experimental Thermal and Fluid Science.
The title of the paper is ‘Influence of a combustion-driven oscillation on global mixing in the flame from a refinery flare'.
An assessment of the influence of strong combustion-driven oscillations on mixing rates and visible radiation in the flame from a full-scale refinery flare is reported. The analysis reveals a consistent picture that the combustion-driven oscillations do not result in a significant change to the global mixing rate, but do increase the visible radiation. This is in contrast to previous investigations, using externally forced jets, where forcing at the preferred mode has been found to increase mixing rates and reduce radiation.
