Investigation of Turbulent Jet Noise with Instability Analysis Method, M.Sc. Thesis Sharif University of Technology ; Afshin, Hossein (Supervisor) ; Farhanieh, Bijan (Supervisor)
Abstract
Acoustic noise from turbulent jet flow discharged to the einvironment is called turbulent jet noise which is a problem for turbojets, turbofans, missiles, rockets and everywhere the discharge of a jet at high speed exists. In order to achieve the jet noise reduction methods, understanding this phenomenon with modeling on a detailed theory for the future developments in this field is required. In this study the noise generation from coherent large scale structures for a subsonic jet with acoustic Mach number of 0.5 is studied using linear stability analysis. To get the base flow used in instability analysis, the jet flow is modeled using different two equation k-ε models and after...
