Parametric Study of Fan Flow Deflectors for Jet Noise Suppression

Abstract

This is continuation of experimental work at U.C. Irvine on fan flow deflection (FFD) [1]. The working principle of FFD is reduction of the convective Mach number of turbulent eddies that generate intense downward and sideward sound radiation. In a coaxial separate-flow turbofan engine this is achieved by tilting in the general downward direction, by a few… (More)
