Teledyne Marine developed a system for the long-range ocean acoustic tomography, which uses a tunable, high-efficiency sound resonator. The high-Q resonator tunes to match the frequency and phase of a reference frequency-modulated signal. The analysis of a high-Q resonant organ pipe with ... Per saperne di più
A frequency-domain finite element (FE) technique for computing the acoustic scattering from axially symmetric fluid-loaded structures subject to a nonsymmetric forcing field based on Ref. 1 is extended to poroelastic media and implemented in COMSOL Multiphysics® software. This method ... Per saperne di più
Tonal noise from wind turbines can have effects on neighboring residences and its emission can result in strong regulatory penalties that can include the closure of wind farms. The authors present a model of a new broadband damping approach where containers filled with EniDamp™, an ... Per saperne di più
The assessment of the seismic safety of gravity dams is a topic of great importance in civil engineering. In this paper, fluid structure interaction modeling of gravity dams during earthquakes is investigated. In particular, this work aims to provide physical significance of a plan ... Per saperne di più
An electrostatic headphone includes many interrelated design elements that affect the frequency response of the headphone and the users listening experience. Xi Engineering Consultants (XI) partnered with Warwick Audio Technologies (WAT) to investigate the complex behavior of one-side ... Per saperne di più
The vibration behavior of carbon fiber reinforced composites (CFRP) specimens with impact damage is presented in order to evaluate if an before/after modal analysis can be used as a non-destructive testing method to detect delaminations. The impact damage is modeled by decreasing the ... Per saperne di più
For automotive applications, simulation methods are used to get the best audio acoustic performance. Because a loudspeaker is a non linear device, the sound pressure in the vehicle includes harmonics which are mainly created by the force factor, suspension stiffness and voice coil ...

When the particles in a colloid come close to each other, multiple scattering in ultrasonic beams is no longer negligible and crowded particle effects emerge. The presence of each particle affects the scattering of all others, leading to coupling effects. We investigate the interaction ... Per saperne di più
Bloch waves in infinite periodic structures – much in vogue in the present metamaterial age – can be conveniently studied by COMSOL Multiphysics® software. This is demonstrated by a simple, yet rich two-dimensional example: a perforated sheet with square symmetry. Instead of plane waves ... Per saperne di più
Airbus Safran Launchers is the market leader in Space Launch services. Rocket engines are among the most powerful machines that exist. The core of the rocket engine is the combustion chamber where in the case of liquid propellant rocket engines, fuel and oxidizer are injected, mixed and ... Per saperne di più
