In this paper, we report FEM studies of the effect of unwanted interfering structural vibrations on the performance of an underwater Acoustic Vector Sensor (AVS) performed in the COMSOL Multiphysics simulation tool. An AVS is a compact sensor that measures a four-dimensional vector ... En savoir plus
Reducing greenhouse gas emissions and finding new ecological and renewable energy sources are among the biggest challenges humanity is facing nowadays [1] [2]. At the same time, power requirements are increasing constantly, where primary energy consumption is intrinsically accompanied by ... En savoir plus
In this paper, we present study on the mass loading effect of the interdigital transducer (IDT) on surface acoustic wave (SAW) velocity in SAW devices, using COMSOL Multiphysics. We have simulated a one port SAW resonator made on YZ lithium niobate substrate and investigated the ... En savoir plus
The continuous inkjet technology is widely used in the industry for marking and coding, and reposes on the emission of charged droplets at high velocity and high frequency. The shape of the droplets and the length needed for the jet breakup are important indicators when designing a ... En savoir plus
Refrigeration plays a crucial role in both industrial and residential sectors, where nearly 17% of the energy consumption worldwide is related to thermal management systems [1] [2]. Furthermore, current vapor-compression refrigeration technology contributes significantly to the ... En savoir plus
Ultrasonic levitation is a novel technology for contactless handing of various objects. It is already used in various manufacturing processes where it is important to keep untouched surface. In this paper we introduce a model of so-called near-field ultrasonic levitation which allows ... En savoir plus
Micro electrical discharge machining (MEDM), a scaled down version of EDM process, is a micro machining process used to fabricate micro holes and intricate shapes in electrically conductive materials irrespective of its hardness. In this process, an electric spark is generated in the gap ... En savoir plus
Started in March 2020, the SOFITT project (Saturated Open-Cell Foams for Innovative Tribology in Turbomachinery), funded by the ANR (French National Research Agency), aims to develop reliable, high-performance, and environmentally friendly solutions for the guidance and support systems ...

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... En savoir plus
