Abstract:

Ignition of unadulterated no added sensitizers, e.g., NO2, Cl2, SO2, unheated room temperature, flowing fuel atomized liquid and gaseous-air mixtures was achieved by exposure to minute energy pulses of vacuum ultraviolet radiation. Experimental and analytical results indicated that ignition energies were essentially constant for mixture velocities below some critical value and then increased linearly with increasing mixture velocity. Further, it has been shown possible to hold a flame photochemically in a flowing mixture by operating the radiant source in a repetitively pulsed mode. Author Modified Abstract
