FORMATION OF MOVING AND STATIONARY DETONATION WAVES IN FLOWING COMBUSTIBLE MIXTURES
Abstract
The report summarizes experiments undertaken to determine the detonation properties of liquid RP-1 sprays in gaseous oxygen as a function of fuel and oxidizer temperature and mixture ratio. One of the more significant results observed was that when both the RP-1 and oxygen were tested to 92C, two different stable modes of detonation, each having a steady speed, occurred in the same experiment. The first detonation mode was non-oscillatory; the second mode was a spinning oscillatory detonation mode with a different constant velocity approximately 100 meters/second below that of the non-oscillatory mode. Induction properties were unrepeatable and random for the most part, leading to little basis for correlation of induction properties with tube diameter or type of igniter. Tube diameter and type of igniter seemed to have little effect on the resultant detonation velocities. The induction distances generally decreased with temperature increase. The large discrepancy found between theoretical and experimental wave speeds were thought to be caused by incomplete burning of the liquid droplets in the detonation wave front.
