Implicit Large Eddy Simulations of 2D Flow and Heat Transfer in Thermoacoustic Resonators
The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic ... 詳細を見る
Parametric Simulation of PZT Diameter to Hole Ratio for Optimized Membrane Displacement
For our simulation we used the Piezoelectric Devices interface. The structure was set with (clamped) fix constraint boundaries to both ends. The bottom electrode was set to be the ground for the electrostatic physics and the top electrode was set to be a Terminal with potential of 10V. A ... 詳細を見る
Toroidal Spring Coil: Displacements & Stress Analysis to Detect the Sealing Parameters
The aim of the simulation is to study the behavior of a particular arrangement of a sealing system made of a Toroidal Spring Coil encapsulated in an thin casing, which is provided with a circumpherential cut to permit the pressure fill it inside. The mechanical simulation implemented ... 詳細を見る
Simulation of the Earth's Electromagnetic Clearance System (DEMETER)
DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also ... 詳細を見る
Modeling of Space-Charge Effects in 3D Thermionic Devices
The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due ... 詳細を見る
Stress Evolution due to EM in Metal Line Confined: Model and Correlation with Experiments
Electromigration induced failure is one of the main reliability issues for the microelectronics industry. The continuous scaling of the interconnect dimensions leads to higher operating current densities and temperatures, which accentuates the electromigration failure. As a consequence, ... 詳細を見る
Dielectric Adaptive Optical Gels
Adaptive Optics is common sense, since many people use digital cameras with electromechanical iris actors on elastic autofocus lenses. This project tries to create a COMSOL Multiphysics based mathematical model of adaptive optics with electrostatically induced deformation of dielectric ... 詳細を見る
Resistive Losses in a 3D Coil
In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the ... 詳細を見る
Multiphysics Studies for the Micromegas Detector
We present studies of the electric field configuration that guides the electrons to the strips through the mesh and its importance to the detector’s optimal operation. Furthermore, analysis of the gas propagation inside the chamber for different gas distribution schemes is discussed. All ... 詳細を見る
First Approach Toward a Modeling of the Impedance Spectroscopic Behavior of Microbial Living Cells
The subject of the interactions between electromagnetic (EM) fields and living cells is a strong issue for several decades [1]. Large number of works have been done to study the EM field penetration and inner induced currents in living microorganisms. Relevant information to be collected ... 詳細を見る
