Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... 詳細を見る
Injection of 3-D hot plume blob develops localized and short-term increases in slab surface temperatures, consistent with the Abukuma adakite, Northeast Japan. 3-D mantle flow develops trough of the lowered slab surface temperatures implying along lowered slab surface temperatures, ... 詳細を見る
The prediction of mechanical response of assemblies during arc welding necessitates the knowledge of thermal history of the components and the constitutive behavior of the materials. COMSOL can simulate thermal and structural interaction but it needs to evaluate the time evolution of ... 詳細を見る
Using COMSOL Multiphysics, a finite element model is introduced in this paper to describe the couplings between the welding arc and the weld pool dynamic in pulsed gas tungsten arc welding. The cathode, arc-plasma and melting anode regions are taken into account. The unified time ... 詳細を見る
The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... 詳細を見る
Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... 詳細を見る
Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... 詳細を見る
The simplicity, reliability and low costs of electro-mechanical breakers have made them the workhorse for the interruption of low voltage short-circuit currents. In the presence of a short circuit, the contacts of the breaker heat up, and a bridge of molten metal forms between the pair ... 詳細を見る
In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... 詳細を見る
COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ... 詳細を見る
