Abstract:
In this work, we report the results of experimental und
computational studies on inhibition and extinction of
opposed-flow propane (C3H8)-air flames by DMMP
(C3H9O3P), as well as N2 and FM-200 (C3F7H) as reference
inhibitors. For the dilute flame conditions used in this
work (high Zst) inhibitor effectiveness was
significantly enhanced compared to previous results with
undiluted fuel. However, unlike the previous work, OH
fluorescence signals, and thus concentrtions, did not
decrease as the inhibitant concentration was increased,
even near extinction. The cause for this mains to be
determined. Modcling results for a 1-D opposed flow
flame of the same conditions agree with the present
results of steady OH levels, while having also predicted
the decreasing levels for the previous work with
undiluted fuel.
