Integrating career development learning into the curriculum: Collaboration with the careers service for employability
Autor: Ruth Bridgstock, Michelle Grant-Iramu, Alan McAlpine
Publikováno v: Journal of Teaching and Learning for Graduate Employability, Vol 10, Iss 1, Pp 56-72 (2019)
Career development learning has a demonstrable positive impact on the graduate employability of higher education learners. This is particularly the case if it is integrated into the curriculum rather than experienced as an add-on or included in finit

An analytical model of sound refraction by the fuselage boundary layer for fan tone radiation from a turbofan aero-engine
Autor: Dionysios-Marios Rouvas, Alan McAlpine
Publikováno v: 28th AIAA/CEAS Aeroacoustics 2022 Conference
28th AIAA/CEAS Aeroacoustics Conference
The work presented in this paper is on the development and validation of an analytical-based model to predict scattering of fan tone noise from a turbofan engine by the airframe fuselage and refraction due to the presence of a boundary layer on the f

Spectral Broadening of Tonal Sound Propagating Through an Axisymmetric Turbulent Shear Layer
Autor: Alan McAlpine, Brian J. Tester
Publikováno v: AIAA Journal. 58:1093-1106
In aeroacoustics, spectral broadening refers to the scattering of tonal sound fields by turbulent shear layers, whereby the interaction of the sound with turbulent flow results in power lost from the tone and distributed into a broadband field around

Slanted septum and multiple folded cavity liners for broadband sound absorption
Autor: Suresh Palani, Daisuke Sasaki, Paul Murray, Christophe Richter, Alan McAlpine
Publikováno v: International Journal of Aeroacoustics
The design of acoustic liners with complex cavities for a wide frequency range of attenuation using numerical method is investigated in this paper. Three novel liner concepts are presented, demonstrating predicted improvements in broadband sound abso

Theoretical Methods for the Prediction of Near-Field and Far-Field Sound Radiation of Fan Tones Scattered By A Cylindrical Fuselage
Autor: Alan McAlpine, Dionysios-Marios Rouvas
Publikováno v: AIAA Aviation 2021 Forum
AIAA AVIATION 2021 FORUM
The aim of the work presented in this paper is the development of theoretical methods to predict scattering of fan tone noise from a turbofan engine by the airframe fuselage. The analysis begins with an overview of previous research on fan tone noise

Optimisation of slanted septum core and multiple folded cavity acoustic liners for aero-engines
Autor: Suresh Palani, Paul Murray, Christoph Richter, Alan McAlpine
Publikováno v: AIAA Aviation 2021 Forum
AIAA AVIATION 2021 FORUM
This paper reports an assessment of the performance of two novel broadband liners for aero-engine applications, under both high sound pressure level and grazing flow. Duct insertion loss predictions are made for the novel liners for downstream sound

On the characteristics of modal radiation from ducts above and below cut-off
Autor: Philip Joseph, Ronnie Leung, Alan McAlpine, Ben Baddour
This work investigates the acoustic radiation from a submerged semi-infinite pipe, such as for marine ducted propellers, which are generally close to the duct open end compared to the acoustic wavelength. Radiation from the duct therefore comprises b
