Sound Generated by Quadrupole Near Object
Aerodynamic sound is generated by unsteady fluid motion and enhanced when the flow becomes turbulent. For example, drone is loud because the ambient air is stirred by their propeller to get lift and movement and the air becomes turbulent. Reduction of aerodynamic noise is an important ... Read More
Electrochemistry Modeling of a Smartphone Based Electrochemiluminescence Sensor
An electrochemiluminescence (ECL) sensor was developed in a smartphone-based platform using a disposable disk-shaped carbon electrode. A time-varying square waveform potential was applied to the working electrode, and the current and ECL intensity data were measured. The applied ... Read More
Thermal Heterogeneity Induced by Smouldering Combustion in Homogeneous Porous Medium
Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... Read More
Numerical Simulation of Mixing with Intermeshing Rotors
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 ... Read More
Prediction of Temperature Distribution in a Laser Powered Homogenous Pyrolysis Reactor
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 ... Read More
Simulation of a Scaled-up Deformable Mirror System Driven by MEMS-Based Lorentz Actuator Arrays
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 ... Read More
Thermal Response of Encapsulants for Photovoltaic Applications
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 ... Read More
Analysis of Large CFRP Plate with Delamination Due to Drop-Weight Impact
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 ... Read More
A Part-Scale Process Simulation App for Laser Powder Bed Fusion
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 ... Read More
Design of a Surface Plasmon Resonance Based S-R Latch Circuit
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 ... Read More
