A Study of Effects of Combustion on the Noise Generated by a Circular Jet Flow

Abstract

The noise generated by the standard Sandia Non-premixed Turbulent Flame Workshop (TNF) DLR-A and DLR-B flames was experimentally studied and compared with the noise generated by a cold air jet from same burner with identical exit Reynolds Numbers (Re). The axial and radial variations were studied for both reacting and non-reacting jets and compared.
