Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery such that the mass transport of glucose around all the micro-electrodes can be improved and hence output ...

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to allow the study of gas phase reactions at low (atmospheric) and high pressures (up to 20 MPa), with the ...

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor / magnetic material configuration, using FEA software to calculate the resulting field, modifying the configuration, and iterating to produce the desired field. Our method involved solving the classical Laplace equation on regions with imposed boundary conditions, which was implemented straightforwardly ...

In the paper distributed parameter system models in the form of lumped-input/distributed-output systems are introduced and modeling of temperature fields of the die in the benchmark casting plant is presented. Temperature fields were modeled and studied using a finite element method based software package COMSOL Multiphysics and numerical models in the form of a lumped-input/distributed-output ...

Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world wide cooperation to achieve this goal, seven parties including Europe, Japan, Russia, USA, China, South-Korea and ...

Cellular ceramic substrates are extensively used for pollution control systems in vehicles. The manufacturing process of them can involve microwave drying. In this study, we describe the development of a modeling framework for the microwave drying process of these substrates. The transport model is implemented in COMSOL 3.5a using 4 PDEs: 1) Convection-Conduction for temperature, 2) ...

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which is ...

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water calorimetry. Since the dose distributions delivered by such beams are nonuniform, temperature signals ...
