Pagination or Media Count:
Several theoretically derived criteria for combustion instability are discussed and their limitations for predicting performance characteristics are pointed out. The effect of various factors such as pressure, temperature gradient, temperature sensitivity, and particle size on the burning velocity are reviewed and their significance for instability is outlined. Other potential elements of combustion instability such as the phase transformations and physical-reaction mechanisms are also treated. Some of the instability mechanisms are discussed together with the possibility of modifying them by proper propellant formulation in order to prevent instability. Various factors affecting stability are summarized. Source material directly and indirectly related to the subject is analyzed. Articles on high- and low-frequency instability, theoretical derivation of stability criteria, and experimental investigations of instability are reviewed. Factors influencing instability are summarized and discussed together with suggested measures for suppressing instability. Author
