The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... Per saperne di più
The paper illustrates the use of COMSOL for obtaining the quantum mechanics wave function Ψ(x,y,z,t) as a solution to the time dependent Schrödinger equation. Once having Ψ(x,y,z,t), it can be used to compute the probability of a particle being in a specific zone within the spatial ... Per saperne di più
This paper describes the Virtual Prototype of a Dielectric Window or High Power Microwave Vacuum Tubes and Linear Accelerators. Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics® software are proposed. The virtual prototype considers the ... Per saperne di più
The vibration of the walls of brass wind instruments has been a subject of study in the field of musical acoustics throughout the last decades. The amplitude of such vibrations, stimulated by the oscillating air pressure inside the instrument bore, is very small compared to the ... Per saperne di più
Industrial fluid systems often involve continuous piping loops. These systems consist of varying lengths of pipes and hoses connecting multiple components together. Fluid resonances can detrimentally affect the operation of fluid systems and components. This work used COMSOL to ... Per saperne di più
Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. Per saperne di più
In this paper we want to figure out the development of a capacitive acceleration-sensor system with the FEM-Method. The sensor-system is in the position to detect accelerations in the range of ±20 g. Furthermore the sensor-element contains a printed RF-inductance, which is used for ... Per saperne di più
Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is ... Per saperne di più
Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of ... Per saperne di più
The Thomson coil’s (TC) inherent characteristics are appropriate to meet the needs of high speed actuators for mechanical switching devices in so-called smart grids. This is due to the massive forces that it can exert in the time scale of milliseconds. A coupled COMSOL Multiphysics model ... Per saperne di più
