The development of a quantitative nondestructive evaluation method, as an alternative to visual inspection, for inspecting pre-tensioned bolts in fracture critical bridges is presented. In order to understand the ultrasonic behavior of a wide variety of bolt geometries used in bridges, ... En savoir plus
Even though the researches in synchronous machines are advanced, the practical design still is a problem because of the complex interaction between several design parameters. The project “EaSync” at the Ostfalia University focuses on the bundling of machine models using COMSOL ... En savoir plus
Vibration and Dynamic performances of the rotating machinery are conventionally evaluated based on the dominant structural forces such as the centrifugal forces. The increase in rotational speed, miniaturization and performance, demands for improved and accurate evaluation of the ... En savoir plus
This paper describes the COMSOL Multiphysics® simulation and the test of a low-frequency (500Hz) sound source for long-range acoustic communications. This design uses innovative carbon-fiber composite materials.To meet the demand for the frequency range the doubly resonant organ pipe ... En savoir plus
Multiphysics optimization of thermal-fluid systems is an emerging area of interest with application to the development of high performance cooling technologies for electronic systems. This paper builds on previous work focused on the development of a computational platform for numerical ... En savoir plus
The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the ... En savoir plus
In this paper, the effects of roughness in the surfaces of the plates caused due to nonuniform etching during their release and/or due to defects in the original wafer on the capacitance in RF-MEMS parallel plate varactors are analyzed. Capacitance extraction due to surface roughness has ... En savoir plus
The finite-element method (FEM) (COMSOL RF Module) has been employed for modal analyses of porous silicon (PSi) waveguides composed of a guiding layer of low porosity (high refractive index) on a cladding layer with higher porosity (lower refractive index). These can be made by switching ... En savoir plus
Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... En savoir plus
Magnetic separation of magnetic liquid phases/particles from non-magnetic liquid phases/particles are needed for applications such as cleaning up oil spills by separating oil and water liquid phases or separating magnetic materials from non-magnetic materials in biomedical and ... En savoir plus
