The value of the stream velocity at point G (separating region II Tom region III) represents the maximum stream velocity beyond which lifted flames do not exist. Region III. 66 m/s, only attached stable flames were observed and these flames remained at- tached to the rim at blowout. 3). As can be seen the flame blowout limit was decreas- ing with an increase in the CO-flowingstream velocity and beyond a certain value of the CO-flowing stream velocity, the stable ftame could not exist at all. It was not possible to ignite a jet when its velocity exceeded the d u e s shown by line PR.

2 Theoretical Studies of FIame Stability st abilization to develop a predictive procedure for evaluating the blowout limits of Liftecl flames in a codned, c d o w h g stream of air. By using velocity and concentration profles for a jet in a cdowing stream measured by Biringen [68], they cdcdated the position where the local flame stabilization rnechanism fails and leads to blowout, This position was assumed to be at the last large coherent structure within the jet at which the concentration of jet fuel reaches its stoichiometricvalue.

The limiting CO-flowingstream velocity increased somewhat 6 t h an increase in the nozzle diameter. 2 Stability Curves for Other Common f i e l s Stability curves similar to those described for methane jet dame were d s o obtained for propane, ethylene and hydrogen. 8. Regions 1, II and III can be ident5ed for all these fuels, however, their relative size depends on the type of a fuel. These regions were &O observed for an unconfined, CO-flowinghydrogen jet flame in air [14]. 00 \ Blowout of lifted flames Blowout of attached flames A Liftoff of attached flarnes O A .
