CORRELATION OF CLASSICAL COMBUSTION QUANTITIES WITH RAMJET BURNER PERFORMANCE,
Abstract
An attempt was made to correlate each of four combustion quantities (hot rod ignition parameter, normal flame velocity, lean inflammability limits, and minimum spark ignition energy) with ramjet burner performance in respect to effect of fuel type on efficiency, effect of fuel additives on efficiency, burner stability limits, and efficiency losses at altitudes. It was found that all of the measured combustion quantities have a definite relation to the first three burner performance characteristics. Although no hot rod work was done at altitude, the second and third combustion quantities do not give practical predictions of the efficiency losses to be expected at lower pressures. Minimum spark ignition energy, however, does serve this purpose. The most interesting point originating from these correlation studies is the development of a single curve for a given burner, which predicts efficiency in terms of minimum spark ignition energy over a wide range of simultaneous variation in pressure and fuel type.
