COMBUSTION INSTABILITY.
Abstract
The principal objective of the program was to relate combustion stability to injector design variables through a consideration of droplet dynamics and combustion. The basic model treats the individual droplets as energy and mass sources. Stability or instability is determined by the relationship between energy and mass addition and the characteristics of the chamber or of a disturbance introduced into the chamber. Depending upon such relationships, a disturbance will be either amplified or dumped. A determination of the stability of a system will depend not only upon the frequency response of the energy and/or mass source but may also depend upon its spatial relationship. One of the first efforts in the study was to determine whether propellant droplets would assume specific patterns with respect to a distrubance and whether these patterns could affect the stability of the combustion process.
