Modeling of the keyhole asymmetry in dissimilar laser welding
An auto-consistent multiphysical 3D model with strong coupling between Heat Transfer, Navier Stokes and ALE problems is proposed for the description of transient development of the keyhole and the melted zone in laser welding of metallic materials. It showed a satisfactory correspondence ... Read More
Optimization of Microfabricated 2D Planar Spiral Microcoils for the Micro NDT of Grinding Burn
Cylindrical grinding has become an integral part of machining of workpieces with an ultra-high precision and higher throughput. The grinding process involves the mechanical interaction of the grinding blade with the workpiece at relatively higher rotation speeds, with a higher energy ... Read More
The modeling of keyhole digging during ablative laser beam interaction with aluminum/magnesium joint
A lateral observation of laser-induced keyhole through the quartz window is an easy and cheap experimental method. It opens an interesting perspective for the study of keyhole asymmetry in case of dissimilar metal combinations. To quantify the effect of quartz window on the observed ... Read More
Thermal performance simulation of phase-change memory cells
The well-known Moore’s ‘Law’ sets a target for the down-scaling of silicon-based electronic devices. The down-scaling of devices may provide better performances, such as increased speed and lower power consumption that lead to a lower cost per bit. This is true for the processor ... Read More
Development of Simulation Model for Pyroclastic Flows using COMSOL Multiphysics®
The experience of the eruption in Montserrat in 1997 has shown that the resistance of openings of buildings represents a crucial factor in the evaluation of vulnerability to the stresses caused by pyroclastic flows, although the static nature of the building itself is not compromised. ... Read More
CFD modelling of a carbonation reactor
The transition to sustainable production includes the reduction of fossil material usage. Vegetable oil can be used as a reagent to form polyurethane by epoxidation through three major reaction steps, epoxidation, carbonation, and aminolysis. Many attempts have been made to model these ... Read More
