In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

A computational investigation was carried out to study and determine the aerodynamics and aeroacoustics of an Airbus A320´s flap side-edge. A detached eddy simulation was performed on geometry that was based upon the airfoil of the flap; in order to understand the flowfield and furthermore develop a future mathematical model that would describe the generation of aircraft on the noise in the flap side-edge. One main source of vorticity in the flowfield was identified from the computational research; the flap side-edge vortical system. This source of vorticity interacted to produce a significantly unsteady flowfield above the solid flap surface. One potential acoustic source on the flap was identified. This was a turbulent shear layer that rolled up to form the flap side-edge vortex, reattaching firstly on the side-edge and secondly on the suction surface of the flap. Measurements taken as part of the computational study were forces, on-surface pressures, sound pressure levels and a vectors simulation were performed to visualise the on-surface flow.
