A Method for Optimal Reconstruction of Velocity Response Using Experimental Displacement and Acceleration Signals
(2007)
An algorithm is developed which takes advantage of the positive characteristics of integration and differentiation operations which can produce an optimal time-domain estimate of
a velocity signal when a displacement and ...
Open Design and the Reprap Project
(2010)
This paper details the investigation of an emerging trend within technology development: `open design?. Improvements in communications and computing technology have made collaboration over geographically vast distances ...
Aeroacoustics research in Europe: The CEAS-ASC report on 2022 highlights
(2024)
The Council of European Aerospace Societies (CEAS) Aeroacoustics Specialists Committee (ASC)
supports and promotes the interests of the scientific and industrial aeroacoustics community
on a European scale and European ...
Aeroacoustic source characterization technique applied to a cylindrical Helmholtz resonator
(2011)
The aim of this work is to investigate the sound produced by a Helmholtz resonator excited
by a boundary layer. A deep cylindrical cavity with a small rectangular opening was designed
to allow Helmholtz resonance as well ...
Heat Transfer Enhancement In Ducts Due To Acoustic Excitation
(2009)
The thermoacoustic effect that results from the interaction of a sound wave in a
compressible fluid in contact with solid boundaries is known to be capable of removing heat from
power dissipating systems. In this paper ...
Acoustic plate-valve resonator for low-frequency sound absorption
(2023)
An acoustic plate-valve resonator is developed and optimized to maximize absorption by enhancing the Helmholtz resonance with coincident structural vibrations of the plate-valve. The current research initially examines the ...
Aeroacoustic Noise Source Identification Using Irregularly Sampled LDV Measurements Coupled with Beamforming (AIAA-2011-2719)
(2011)
This paper develops a technique which relates dynamic pressure measurements taken
outside the hydrodynamic eld of a low speed jet to single point, one component velocity
measurements taken within the jet using a Laser ...
Multi-chamber micro-perforated panel absorbers optimised for high amplitude broadband absorption using a two-point impedance method
(2023)
An optimised, multi-chamber, micro-perforated panel absorber (MC-MPPA) with micro-perforated adjoining panels is presented in this paper. An MPPA is a clean and efficient noise absorber with a simple structure making it ...
