Finite Element Analysis of Planar Microcoil Based Induction-balance Magnetic MEMS Sensor
Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... Read More
Simulation of Helium Atmospheric Pressure Plasma Jet using COMSOL Multiphysics®
Atmospheric-pressure plasma jets (APPJ) are devices that generate chemically reactive species and operate at atmospheric pressure and ambient temperature for a wide range of applications. Plasmas jets produce charged particles (electrons and ions), neutral metastable species, radicals, ... Read More
Modeling Joule-Thomson Effect with COMSOL Multiphysics®
Joule-Thomson effect describes a change of temperature in a fluid due to a sudden change of pressure under adiabatic conditions. The aim of this study is to reproduce Joule-Thomson effect when an incompressible gas flows through a narrow pipe connecting two tanks at different pressures. ... Read More
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
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
Thermal Analysis of DED process and COMSOL Multiphysics® feasibility in Mechanical Modeling of AM process
COMSOL Multiphysics® is being utilised to develop Thermal Model for Directed Energy Deposition (DED) process with an objective to analyse the heat transfer phenomenon during and after the process. With the rapid growth of industrial acceptance of DED process, different research ... Read More
Numerical Modeling of Single-Phase Fluid-Flow in Wavy Micro-Channels
High power-density electronic devices had achieved levels of heat generation that have exceed the current heat removal capacities. Due to the increase in power density of modern electronic chips, there is a need of a higher heat flux removal capabilities, and single-phase fluid-flow wavy ... Read More
