Abstract
Flame attachment and liftoff is examined using scaling methods. Three regimes of practical and theoretical interest are described: (1) a very slow flow regime; (2) a slow flow regime; (3) a moderate flow regime. Correlations for flame quenching distance and characteristic flame width versus flow rate are developed for regimes (2) and (3). Regime (1) is independent of the flow rate. For moderate to large values the flow rate dictates flame structure changes relative to liftoff height, whereas for low flow rates the sensitivity to reaction rate controls the flame response. Comparisons with four different groups of experiments are favorable despite the fact that the experimental conditions differ from the model configuration. A liftoff height versus flow rate plot based partly on present results is constructed.
