THEORETICAL CONSIDERATIONS ON THE NATURE OF SCREECHING OSCILLATION,

Abstract

A review of available data on the nature of screeching combustion is given to show that there is considerable disagreement between investigators. To resolve this difficulty, a linearized theory of thermally sustained sound waves is developed. There are two types of screech, one self-maintained, the other a driven or forced oscillation. For self-maintained screech, the frequency is inversely proportional to the burner diameter, and the pressure and inlet gas velocity determine the equivalence ratio screech limits. (Author)
