Interactions between the Flow Field, Combustion, and Wave Motions in Rocket Motors

Abstract

The stability of small amplitude oscillations in combustion chambers is analyzed for one- and three-dimensional problems. In addition to combustion and mass addition at the boundaries, residual combustion and the presence of particulate matter within the chamber are accounted for. The results for the one-dimensional problem introduce new contributions, to the balance of acoustic energy, associated essentially with boundary layer processes acting if there is a component of acoustical motion parallel to the surface. These are incorporated in the general three-dimensional problem, and are shown to have a significant influence on the predicted stability of motions in a rocket motor.
