Multiphysics Design of ESS-Bilbao Linac Accelerating Cavities Using COMSOL
A proton linac drives particles using the electric field of a high power RF standing wave in a resonant cavity. The design of these cavities involve several aspects of multiphysics simulation, that have been accomplished using COMSOL. The first step consist on the geometric optimization ... Read More
High Frequency Magnetohydrodynamic Calculations in COMSOL
In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only ... Read More
Numerical Simulation for Dimensioning a Rock Heating Experiment
The paper deals with simulation of rock heating experiment in underground, testing the rock properties for geothermal application. The modeled process is unsteady heat conduction in 3D. We made several parametric studies to find the possible temperature range with uncertainty in some of ... Read More
Mass Transfer From a Rotating Cylinder in a Confined Gas Flow
The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar ... Read More
Finite Element Approach for the Analysis of the Fuel Cell Internal Stress Distribution
A fuel cell stack is a setup of a number of single fuel cells which have to be mechanically compressed each other to ensure good electrical conductivities and tightness against leakage of supplying gases (e.g. hydrogen) and cooling media. In this study a 3D FEM model is developed with ... Read More
Three Dimensional Numerical Study of the Interaction of Turbulent Liquid Metal Flow with an External Magnetic Field
Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... Read More
Design and Development, via Prototype Testing and Multiphysics Modelling, of a Thermoelectric Generator (TEG) for Integration in Autonomous Gas Heaters
An autonomous gas-heater for outdoor environments was selected as a test-case for cogeneration in gas-heaters and stoves, permitting installation and operation without need of an electrical network connection. A thermoelectric generator (TEG) was designed, converting part of produced ... Read More
Analysis Of Linearly Polarized Modes
This paper presents a study on the propagation modes of electromagnetic waves through a step index fiber optics. To analyze the propagation of electromagnetic field, a simulation in Comsol 4.0 has been implemented using two different optical fibers. Obtaining the propagation modes, ... Read More
Numerical Homogenization in Multi-scale Models of Musculoskeletal Mineralized Tissues
Musculoskeletal mineralized tissues (MMTs), e.g. bone, are hierarchical composite materials. Their effective elastic properties at different scales are of interest for computational studies of the MMT’s response to mechanical loading but also to realistically simulate implant ... Read More
Design and Characterization of a Novel High-g Accelerometer
The Fraunhofer Ernst-Mach-Institute (EMI) developed a novel, high-g accelerometer, which is an undamped MEMS device, containing self-supporting piezoresistive elements. The main requirements for such a sensor are high sensitivity, high resonant frequency and a solid mechanical design. ... Read More
