In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post ... En savoir plus

An Acoustic Vector Sensor (AVS) is a compact device used for finding azimuthal as well as elevation angle of an acoustic source using particle velocity and pressure measured at the acoustic center of the device. There are mainly two types of AVS; namely P-P and P-U based AVS. P-P based ... En savoir plus

Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate ... En savoir plus

This paper is an investigation into the effect of blood vessel movement on measurement accuracy of blood flow rate using magnetic flow meters. The investigation used a Finite Element model of the magnetic flowmeter built using COMSOL Multiphysics® software by integrating the modules of ... En savoir plus

The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... En savoir plus

We discuss the use of COMSOL Multiphysics 3.4 in the aerodynamic optimization process of the UNLV solarpowered UAV. We also address the use of COMSOL’s Multiphysics ability and how it was used within the scope of the project. In particular we highlight the development of wingtip devices, ... En savoir plus

A synthetic Jet actuator is a device which moves a fluid in and outside a cavity, through a small aperture, by the continuous oscillation of a diaphragm. The multiphysics interaction between the piezoelectric disk, which deforms due to the alternating voltage, and the fluid makes COMSOL ... En savoir plus

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 ... En savoir plus

The interaction of a single particle in straight rectangular channel in laminar flow is modelled explicitly using the set of Navier Stokes equation for the fluid motion and Newton momentum equation for the particle motion in Cartesian coordinate system. The evaluation of integral force ... En savoir plus

Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible ... En savoir plus
