Understanding the Magnetic Field Penetration in Mesoscopic Superconductors via COMSOL Multiphysics® Software nuovo

I. G. de Oliveira[1]
[1]Universidade Federal Rural do Rio de Janeiro, Seropédica, RJ, Brazil

Introduction: One of the main characteristic of the superconductors is its diamagnetic response of applied magnetic fields. The superconductors refuse the penetration of magnetic field into its interior, it is the well know Meissner effect, B=0 into the superconductor sample. However ... Per saperne di più

It allows for the effect on electric field intensity at the tip of the water tree and electric potential due to the water tree to be better understood. Also, COMSOL is used to ... Per saperne di più

A Phase Field Approach to Model Laser Power Control in Spot Laser Welding nuovo

C. Touvrey[1], V. Bruyere[2], P. Namy[2]
[1]CEA DAM, Valduc, France
[2]SIMTEC, Grenoble, France

Spot laser welding is largely used in industrial manufacturing, especially in the case of small penetration depth. Unfortunately, welded joins are often polluted by porosities. The formation of porosities depends on complex thermo-hydraulic phenomena. During the interaction, a deep ... Per saperne di più
