In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation direction into the waveguide. Maxwell’s equations and heat transfer are coupled to a microbial inactivation ...

Utilization of bioreactors to regenerate tissues outside the body has been intensely investigated in functional tissue engineering. Various studies have been performed using computational fluid dynamics (CFD) to understand fluid flow within bioreactors while assuming porous scaffold as a rigid structure. However, the physical and mechanical properties of most tissue engineering scaffolds suggest ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission ...

Electrokinetic transport of fluids has been investigated both experimentally and numerically due to its various applications in microfluidic devices [1-5]. These devices offer the advantage of transporting fluids or particles to specific locations without the aid of mechanical components. The device by Green et al consists of a symmetric arrangement of CPE subjected to an AC potential [6-8]. The ...

Non contact charging of electronic equipment from mobiles to electric vehicle has created immense interest among researchers. There are various groups working on both radiative and non-radiative energy transfer. The idea based on strongly coupled magnetic resonances is of interest because of the increased distance of energy transfer. This technology based on resonant magnetic coupling with the ...

Microstructures such as holes, grooves, microchannels, and surface texture are essential geometric profiles for micro-components. Burs can cause interference, affect the positioning of processing, and influence the quality and surface appearance of the structure. Electrochemical machining (ECM) is a method of manufacturing that removes metal by electrochemical process instead of conventional ...

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an ...

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, thus, narrow bandwidth. Therefore, it requires optimal mechanical design of the cavities to minimize the ...

Radio frequency (RF) micro-electro mechanical system(MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact to shunt the RF signal. Surface contact area has been recognized as a key factor in RF MEMS performance and reliability. Multi scale regular-fractal structure is observed on MEMS surface. Nonlinear Structural ...

In the nuclear fuel cycle, fluorine is produced by the electrolysis of the molten salt KF-2HF. It is a complex process to study since hydrofluoric acid and fluorine are hazardous and highly corrosive. A 3D-model of a lab-scale fluorine electrolysis cell has been developed to increase our understanding of this process, using the electric currents and the bubbly flow interfaces to simulate the ...
