Modelling Thermal Capillary Effects and Flow in the Molten Pool During Selective Laser Melting
Laser additive manufacturing has become an interesting field of engineering which is revolutionizing industrial processes. Selective Laser melting (SLM) is a widely used additive manufacturing technique for 3D printing of metal structures. This process has a particular complexity in ... En savoir plus
Finite Element Analysis of Accelerating Projectile Inside Vacuum Bazooka
Different modules and capabilities of COMSOL Multi-physics software i.e. Fluid Flow, Moving Mesh and Global ODEs/DAEs are combined and applied to study the accelerating of a projectile inside a so-called "vacuum bazooka". Initially, the projectile is at rest in a partially vacuumed tube. ... En savoir plus
Vibro-acoustic modeling, analysis and optimization using COMSOL Multiphysics
Vibro-acoustics encompasses the study of interaction between sound and vibration. For example, sound transmission analysis is important to design vehicle bodies and building partitions, advanced noise control technologies can ease the increasing noise pollution problem in densely ... En savoir plus
Numerical Simulations of Condensing Moist Air Around Cold Cylinder
In this study numerical simulations of moist air flow around cold cylinder are investigated. The condensation of moist air on the cold cylinder can effect the heat transfer and fluid flow around the cylinder. This physical phenomenon is encountered in a number of industrial processes ...

Red Blood Cell Separation Using Magnetophoresis Force
The separation of RBCs is needed in many biomedical devices. RBCs contain hemoglobin, which in turn consists of iron that helps transport oxygen throughout the body. The permeability of deoxygenated red blood cells is about (1 – 3.9e-6). The permeability of oxygenated red blood cells is ... En savoir plus
Towards Multiscale Models for Bioimpedance of Human Skin with COMSOL Multiphysics
Mechanistic mathematical modeling for electrical impedance spectroscopy (EIS) of human skin involves not only the equation of change for the alternating current from and to the electrodes of the EIS probe but also the spatial resolution of the various skin layers and their material ...

Comparative Analysis of Array 2×2 Double Bi Circular Microstrip Antenna with the Empirical Formula
Comparative Analysis of Array 2x2 Double Bi-Circular Microstrip Antenna was started by doing numeric analysis with empirical formula that supports the counting in relation to the characteristics antenna that is optimally applied in Wi-Fi communication system. The result of analysis that ... En savoir plus
Improvement in Broadband Noise Attenuation with Periodic Top-edge of Noise Barriers
With every passing decade, the issue of noise pollution became worse in urban areas and the usefulness of noise barriers increased. With the increase in demand came the challenge of improving the effectiveness of barriers. To facilitate this, extensive studies have been conducted ... En savoir plus
Numerical Analysis of Flow Chamber Morphologies for Pilot-Scale Ultrasonication
Ultrasonication effectiveness is an important consideration in the scale-up of lab-scale dispersion experiments. Unlike lab-scale experimentation, which can take advantage of localized tools such as probe and bath sonicators, pilot-scale processes may necessitate the use of large flow ... En savoir plus
Effects of Acoustic Scattering on the Active Control of Noise Through Apertures
Active noise control systems have recently been proposed and implemented on domestic window apertures. However, their fundamental limits, and performance in the presence of glass windows has not been studied in detail. The passive acoustic attenuation through an aperture covered with ... En savoir plus
