Simulation of a Thermoelectric Spiral Structure
Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics ... Per saperne di più
FEM Modeling in Robust Design for Graphene-Based Electromagnetic Shielding
Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. ...

Creep Deformation Behavior of Heating Filaments in High Temperature Applications
Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace ... Per saperne di più

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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
