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 ...

1. Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. 2. For a weak soft palate, complete flow occlusion can occur (sleep apnea). 3. Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing-related disorders.

The optimisation of dimensions, materials choice of heaters in annealing furnaces are done with COMSOL Multiphysics® in 2D-axisymetry. Heat losses sources are identified and corrective actions can be taken in function of simulation results. A power saving of more than 50% is achieved thanks to simulations.

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD . A virtual pharmacokinetic 3D model of the human eye is built to address this problem, using COMSOL Multiphysics® software, based on the Finite ...

A Polysilicon H-beam is a micro-machined structure consisting of two primary members connected by a third member of much lower width and much greater aspect ratio. This structure exhibits interesting vibration behavior at specific frequencies which are known as resonant modes. A ‘mode’ may be described as a specific physical shape that the vibrating object assumes at peak oscillation amplitude ...
