Today, low noise is a mandatory feature for power transformers to comply with customer specifications and environmental regulations. Therefore, it is crucial to develop sound prediction tools with sufficient accuracy to avoid overkill margins in design and costly modifications after ... Per saperne di più
Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... Per saperne di più
The feasibility of phase-sensitive detection of angular-rates using bi-directional orbiting piezoresonators suspended by thick annular springs with thin-film aluminium nitride piezoactuators on top of them was investigated. The ring-shaped flexures are more suitable for supporting the ... Per saperne di più
In this work, we have taken a model which is simulated using COMSOL Multiphysics®. It was used as a tool to design, characterize and to simulate an example which is nanofibers based piezoelectric energy generators. The results are compared with other available sources but using with ... Per saperne di più
This paper describes the use of COMSOL Multiphysics® during the design of a vented box loudspeaker. Templates have been created to model the different needs of a complete design. Based upon those templates a box has been prototyped, measured and confronted to simulation. The cabinet may ... Per saperne di più
The thermoacoustic combustion instabilities are complex phenomena that may occur in steady flow combustion systems that are aboard of, e.g., rocket engines or gas turbines. The phenomena involve the interaction of chemical reactions with fluid-dynamic and propagation of pressure waves in ... Per saperne di più
The paper presents a methodology to account for local mean-flow effects on thermo-acoustic instabilities to improve typical calculations performed under the zero-Mach number assumption. A 3D FEM model of a simplified combustor is solved with COMSOL Multiphysics® Pressure Acoustics ... Per saperne di più
This work enunciates the principles of SAW design from a physical perspective, examining the standard engineering modelling assumptions in some detail. An integral form analytical expression based on 2D elastic isotropic theory is validated against a COMSOL Multiphysics® simulation, ... Per saperne di più
Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... Per saperne di più
In this numerical study, surface acoustic waves (SAWs) are evaluated as a potential disruptive flow technology for enhancing heat transfer in microchannels. Using COMSOL Multiphysics® software, the physics governing acoustics, single-phase-fluid flow and heat transfer are coupled. The ... Per saperne di più
