Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs exclusively use Solid Oxide Fuel Cells with some developments in high temperature polymer electrolyte membranes ...

Chemical vapor deposition (CVD) is widely used in various fields including the fabrication of electronic devices due to its uniform film formation capability on the large-scale wafers and the minute 3D structures. In CVD, precursors (metal compounds) are commonly reacted in gas-phase as well as on the substrate to yield a film, and thereby it is rather difficult to reveal the reaction mechanism ...
Interaction between Light Wave and Asymmetric Metal/Insulator/Metal (MM) Structure Coupled with Subwavelength Holes at Optical Fiber Apex
Osaka University, Suita, Osaka, Japan
Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of asymmetric metal/insulator/metal (MIM) layers coupled with subwavelength holes. Behavior of surface plasmon ...
Analysis of Temperature Distribution in a Magnetite Catalyst Bed under Microwave Irradiation using COMSOL Multiphysics®

Dehydrogenation of ethylbenzene with a magnetite catalyst has been performed with a fixed bed flow type reactor under microwave irradiation. Microwave heating showed a temperature gradient in the catalyst bed. We analyzed an electromagnetic field and heat transfer in the microwave cavity using COMSOL Multiphysics to visualize the temperature distribution in the catalyst bed.

In this report I study the airflow through ventilation ducts. By numerical simulation, the so-called k-factor has been estimated. The k-factor is the quotient of the airflow volume and the square root of the pressure drop over the duct. A two dimensional axial symmetric model has been used to simulate an iris damper connected to a straight pipe. A three dimensional model has been used to ...

Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby yielding continuous change in the direction of streamlines. Experiments as well as simulations (in COMSOL ...

In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, rectangle, square & conical and different compositions such as Al/Steel Alloy and Fe/Cu which can withstand ...

Micro cantilevers are the basic MEMS structures, which can be used both as sensors and actuators. The . The objective of this work is to study concept of pull-in voltage and how to reduce the same. Voltage is applied to upper cantilever beam and lower contact electrode is made as ground. By increasing common area between cantilever beam and contact electrode, and also by reducing thickness of the ...

One of the major challenges faced by the semiconductor industry is that electronic circuits produce a lot of heat energy during their operation. And with the current scenario where the gates are packed so much close together, then the problem of heat generation has become extremely significant. So we are working towards the efficient heat management and dissipation solution for the heat generated ...

In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on the MNE-tips leads to a situation comparable to the whole-cell mode in classical Patch Clamp. MNE-penetration ...
