For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra-logistic. Physical properties of the inductive transfer are modeled via COMSOL. Lumped parameters are deduced from ...

Laminar flow static mixers are accurate, inexpensive fluid mixing devices that can handle a wide range of fluids and mixing proportions. They have a wide range of industrial applications, especially in the consumer product, pharmaceutical, biomedical, and petrochemical industries. A good mixing quality is obtained when the outlet of the mixer has no concentrated volumes of either mixed materials ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission lines ...

The research aims to clarify some aspects of the thermo-fluid dynamics of woody biomass flue gas, within the twisted conduit inside the heat accumulation stoves, and exposes also some analysis about the heat transport and heat exchange processes. The high temperature flue gas flows in the conduit, releasing heat to the refractory. The heat stored in the refractory is then released to the ...

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for fulfilling these roles and continuing with the project until its production phase. The simulation is built with very ...

The Jecklin Disk is a sound absorbing disk placed between two omnidirectional microphones. It is used to recreate some of the frequency-response, time and amplitude variations human listeners’ experience, but in such a way that the recordings also produce a useable stereo image through loudspeakers. This paper presents a finite element model able to simulate the effects on sound propagation ...

The paper presents recent results concerning the experimental mechanical characterization, the numerical modeling and the design of micro-needles used in the construction of probe heads for wafer testing. A fully coupled electro-thermal model was created using COMSOL and combined to a research-oriented thermo-mechanical Finite Element (FE) code in order to accurately reproduce the micro-needle ...

PEM fuel cells are very promising for portable applications. A key component of fuel cell is the flow field plate through which hydrogen will reach the anode, oxygen will reach the cathode and electron collection. Flow field plate made of silicon is not a good electrical conductor , so electrical contacts has to be attached to the Gas Diffusion Layer (GDL) for taking the power to outside ...

The numerical model can be dynamically modified and analyzed by using the COMSOL Java API. We estimated the relative permittivity, diameter and position of the dielectric in a experiment device based on the electric potential and the capacitance of experimental results. The estimation method was developed by the COMSOL Java API and Genetic Algorithm. In this presentation, we will introduce a ...
