An evaluation of the combustion temperature profile of Ba(NO3)2-based composition

The study examined both theoretical and experimental combustion temperatures of Ba(NO3)2-based samples of composition with an oxidizer excess coefficient of α~0.72 under various pressures. The results indicate that at low pressures, the combustion temperature of the samples is significantly lower than the calculated value. The temperature profile in the combustion wave at atmospheric pressure was determined, revealing that the samples exhibit a high surface combustion temperature. The majority of the heat required for the propagation of the sample's combustion is released in the condensed phase. These findings underscore the influence of pressure on combustion characteristics and emphasize the importance of considering phase interactions in understanding combustion behaviors.
