The problem under investigation is electrical scale-up of a generic metallurgical process for primary metal production through resistive heating of slag by electric current, typically supplied by an AC three-phase system. Maxwell’s equations are analyzed revealing that the properties of the solution is determined by the parameter (L/δ)^2, where L is the linear size of the system and δ is the ...

We are investigating gold-plated micromachined silicon integrating cavities for arrays of far infrared Transition Edge Sensor bolometers. We present the results of our simulations and show how we used COMSOL Multiphysics® software to optimize the geometry of the integrating cavity. We show that we can achieve a high optical efficiency over a wide frequency range.

Introdução: A medição adequada de vazão de fluidos é de grande importância nos processos industriais, pois tem implicações diretas na qualidade, produtividade, segurança e eficiência dos processos. Assim, torna-se necessário compreendermos como os fluidos se comportam para baixas velocidades, podendo, dessa forma, projetar estruturas que possam trabalhar em uma faixa de operação mais larga ou ...

Mixing is an important process in a microfluidic system such as micro total analysis systems. In this paper, design and analysis of various micro-mixers for enhancing the mixing performance is presented. At first, the basic principles of mixing along with the mixing length and mixing time calculations are discussed. In general, macro-scale mixing is achieved with turbulence while mixing in micro ...

Sensors have diverse applications ranging from medical field to space explorations. They convert physical parameters such as temperature, pressure, humidity etc: - into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of pressure sensors. Improvement in the sensitivity is the major factor to be considered while designing pressure ...

INTRODUCTION: Nuclear magnetic resonance (NMR) spectroscopy is a broadly used research technique that exploits the magnetic properties of atomic nuclei with non-zero spin in order to determine the physical/chemical properties of the molecules in which they are contained. However, NMR has fundamental sensitivity limitations, as a consequence of the small energy difference between nuclear spin ...

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of these devices becomes of extreme importance in order to enable the required switching capabilities. This ...

We calculate the maximum force acting on the mirror and found it to be 0.54 µN at 700 V. The force magnitude can be improved by increasing voltage and diminishing the separation between plates. The force along X, Y-axis acts towards the center of the plates and in Z direction towards the plates to which the mass is closer.

Motivated from previous studies, the present work developed a computational model of pulsatile blood flow through a bifurcation of artery with stenosis subjects to external body acceleration. The blood is treated as a Newtonian fluid. The flow is modelled as an incompressible and laminar flow passing through a bifurcated channel with an asymmetric obstruction representing a stenosis (see Figure ...

Fouling and cleaning processes present a major impact to the manufacturing industry in terms of economics, product quality, product safety, and plant efficiency. An efficient cleaning process is essential is order to remove fouling to maintain quality and safety of production process as well as the product. Thus, cleaning should be done with minimum cost and time, and understanding soil ...
