Research on Noise Generated by Ducted Air-Fuel Combustion Systems.
Abstract
A two-pronged approach to the study of noise generation by combustion in a confined flow system, similar to a jet engine configuration, has been followed. One aspect deals with the mechanisms of noise generation by combustion; the other aspect deals with the effect of confinement on the noise generation and radiating properties of an unsteady combustion-duct-flow interaction. Mechanisms of sound generation, amplification and scattering by various combustion systems have been studied on theoretical bases compatible with the contemporary understanding of unsteady burning processes. Sound generation mechanisms are classified into categories relating to the Smith-Kilham emission mechanism and the turbulent driven Rijke-Riess emission mechanism. (Modified author abstract)
