In this work. we repoil the results of experimental and con1put:itioiial studies on inhibition and extinction of opposed-flow propane (C&)-air tlaines by DMMP (CxH.,OIP). as well as N? and FM-200 (CIF7H) as reference inhibitors. For the dilute flame conditions used in this work (high Z,,), inhibitor effectiveness was si&rnificantly enhanced compared tu previous results with undiluted fuel. However, unlike the previous wwk. OH fluorescence signals. and thus concentrations. did not decrease as the inhibitant concentration wab increased, even near extinction. The cause for this i.emains to be determinrd. Modeling results for a I-D opposrd flow flainc ofthe smie conditions agree with the present results of strady OH levels, while having iilso predicted the decreasing levels fkr the pi-evious work with undiluted fuel.
