INTERACTION BETWEEN SOUND AND FLOW IN ACOUSTIC CAVITIES: MASS, MOMENTUM, AND ENERGY CONSIDERATIONS,
Abstract
This paper investigates requirements for neutral acoustic stability in cavities with a transpiring wall where there is a mean flow in the absence of acoustic disturbances. The growth rates of the acoustic fields are also considered, and the results are shown to be in agreement with those calculated from first-order admittance considerations. The effect of mean flow is often of considerable importance, and the extent to which flow tends to excite or damp the acoustic field is related to mode configuration and flow field geometry. Application to the problem of determining the acoustic response of burning rocket propellants is discussed. (Author)
