Mixing processes driven by rotating machinery are common in many engineering applications, and the simulation of such processes can aid in understanding and optimizing the mass, momentum, and energy transport in these systems. COMSOL Multiphysics® contains built-in functionality for ... En savoir plus
Laser Powered Homogenous Pyrolysis (LPHP), a non-isothermal wall-less plug flow reactor using cw-IR CO2 laser heating by fast vibrational–translational (V–T) energy transfer, is a common technique for high temperature pyrolysis in the gas phase with minimal catalytic effect of hot ...

This paper presents the design and simulation results of a MEMS-actuated deformable mirror (DM) consisting of a 20 × 20 Lorentz-force actuator array bonded to a flexible mirror. The DM is the critical component of an Adaptive Optics (AO) system targeted for ground-based telescope ... En savoir plus
Photovoltaic (PV) devices on its operational life are exposed to the action of environmental conditions, which can produce damage either chemically or mechanically. For this reason, traditional PV panels are made of different materials including glass, encapsulant, solar cells, backsheet ... En savoir plus
Introduction: The influence of delamination in a small area of a large composite plate due to drop-weight impact was studied in this work. Layerwise theory was only applied to the delamination area to save computational memory. The vibration analysis coupling composite shell and acoustic ... En savoir plus
The laser powder bed fusion (LPBF) process involves a highly localized laser heating, resulting in a large thermal gradient that induces residual thermal stress and deformation in the finished build. The excessive residual deformation in the direction normal to in the process plane could ... En savoir plus
Surface plasmon polaritons are electromagnetic modes excited at the conducting-dielectric interface owing to the resonant interaction between incident photons and free electrons at the conducting surface. Plasmonic resonances confine optical power at subwavelength scales, which allows ... En savoir plus
Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... En savoir plus
One of the most destructive modes of corrosion of metals is localized corrosion. This can take many forms depending on the chemical and electrochemical environment of the metal. One important form is crevice corrosion, which occurs where two or more surfaces in close proximity lead to ... En savoir plus
Soft lossy viscoelastic polymers can dissipate significant amounts of energy in the form of heat when subjected to dynamic mechanical stimuli. As a result, structures comprised of such lossy materials may heat up considerably when excited by loads at a frequency that approaches one of ... En savoir plus
