Microwave drying processes are critical components in the manufacture of cellular ceramic substrates and filters. The objective of this study is to develop a comprehensive model at a small scale and include all the possible physics that are important during microwave drying processes. ... En savoir plus
In this study, a capability has been developed for modeling the linear viscoelastic behaviour of a glassy polymer using COMSOL Multiphysics®. The two rheological models by Maxwell and Kelvin-Voigt were used for modeling stress relaxation and creep loading behavior, respectively, of a ... En savoir plus
Laser thermal treatment (LTT) systems have applications in IC fabrication for improving low-k dielectrics properties, polymer curing and resist processing. This contribution deals with a transient model of fast scanning and pulsing laser multi-beam system used in semiconductor ... En savoir plus
Silicon electrodes are presently being pursued as the potential negative electrode for lithium-ion batteries owing to its high gravimetric (mAh/g) and volumetric capacity (mAh/L) compared to the existing state of the art graphite electrode. Recent experimental studies have demonstrated ... En savoir plus
Finite element models, which include the shielding characteristics of superconductors are often complex and would currently not allow us to study 3D models of devices of complex geometry such as fault current limiters. We propose instead a model based on variable electric conductivity, ... En savoir plus
This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which ... En savoir plus
Sintering is an important step in the manufacturing of polytetrafluoroethylene (PTFE) billets. The challenge in heating large billets stems from the inherent low thermal conductivity of PTFE. Existing literature suggests determining maximum heating rate experimentally using recommended ... En savoir plus
Aluminum alloys 5000 series are widely used within the cabins of ships. These aluminum alloys are often joined via steel bolts. There is thus a concern that galvanic interactions will exacerbate corrosion of the aluminum alloys. In this study, a model of the galvanic corrosion between ... En savoir plus
Simulations with COMSOL Multiphysics were performed, in order to analyze the gas flow patterns during the induced ignition of gases. Simplified calculations were performed. The ignition spark was assumed to have a temperature of 2000 K and a laminar flow was selected. 2D calculations ... En savoir plus
Electroplating is a vital technology widely employed for many technological applications ranging from decorative or anti-corrosion coatings to high precision nanotechnology passive electromagnetic cloaking devices. This 2D Axisymmetric Electroplating Model demonstrates one of the ... En savoir plus
