Unified Aeroacoustics Analysis for High Speed Turboprop Aerodynamics and Noise.Volume 5: Propagation of Propeller Tone Noise Through a Fuselage Boundary Layer

摘要

An analysis of tone noise propagation through a boundary layer and fuselagescattering effects was derived. This analysis is a three dimensional and the complete wave field is solved by matching analytical expressions for the incident and scattered waves in the outer flow to a numerical solution in the boundary layer flow. The outer wave field is constructed analytically from an incident wave appropriate to the source and a scattered wave in the standard Hankel
