Currently in the semiconductor industry more than 80% of silicon crystal are grown by the Czochralski (Cz) method. In this method, fused silica (SiO2) crucibles and graphite heaters are used inside furnaces. The surface of the crucibles, which are in contact with the molten silicon, is ... 詳細を見る

Here we optimize the geometry: proof mass length Lm to total length L, thickness of the piezoelectric material (Tp) to total cantilever thickness (T) for obtaining the maximum stress distribution (Smax), output voltage (Vout) and power performance (Pout) of the unimorph Cantilever beam ... 詳細を見る

In order to improve the design of an induction furnace and to optimize the charge melting, a COMSOL Multiphysics® application is developed. This application runs a furnace model. The inductor, supplied with an alternative electrical tension, creates a variable induction field B ⃗. Due to ... 詳細を見る

Air core reactors are commonly used as shunt reactors, fault current limiting reactors, tuning reactors in capacitor banks. The absence of the iron-core results in a simple and lightweight construction. Consequently, the magnetic field of an air-core reactor is not guided within a ... 詳細を見る

Aluminum production potlines operate under significant amperage in a range of 200 kA – 600 kA. High electrical DC currents induce strong magnetic fields. MHD stability, which is a result of electrical current and magnetic field interaction within aluminum reduction cell, is one of highly ... 詳細を見る

This study models the energy harvesting reached from an air flow transportation through the flapping of a cantilever polymer flag. The mechanical resonance of the flag is created by a Venturi channel. The flag is charged by triboelectrification and its flapping between two electrodes ... 詳細を見る

Circular particle accelerators are powerful tools used in the field of high-energy physics to investigate the nature of the matter. They use strong magnetic fields to bend and focus the particle beams and generate collisions, which are thoroughly analyzed. New physical phenomena may be ... 詳細を見る

Induction heating is used in lot of applications: forging, brazing, hardening, melting, bonding. The main advantage is ability to heat quickly, efficiently, and locally with a good repeatability. It leads to productivity and energy efficiency improvement. These solutions are often used ... 詳細を見る

The vacuum arc remelting is a refining process used to melt reactive metals like titanium, zirconium or hafnium. Melting is performed under vacuum to avoid reactions between liquid metal and oxygen which could be a source of pollution. This process is particularly well suited to purify ... 詳細を見る

The study of low energy electrons (0-300 eV) and especially secondary electrons (typically < 50 eV) are of technical importance in many areas such as Scanning Electron Microscopes [1], spacecraft charging [2], the electron cloud effect in particle accelerators [3] and in radiological ... 詳細を見る
