Abstract: Bone cells have been known to sense extremely weak magnetic fields with very small potential gradients. Several interaction mechanisms have been proposed, in order to explain this phenomenon, but, none of them have yet been able to explain this satisfactorily. A simple arrangement of osteocytes, connected by gap junctions via their processes have been modeled, under the influence of a weak electromagnetic field. The effect of varying the gap junctional conductance has been considered in this model (which corresponds to the degree to which the gap junctions are open, or closed). A Finite element solver (FEMLAB) that considers the conductivity and permittivity of the membranes, intra and extracellular fluid, and the gap junctions has been used. A significant difference in the current density distribution and magnitude is observed for a large change in gap junctional conductance. (7 refs.)

Computational analysis of temperature rise phenomena in electric induction motors

Abstract: In developing electric machines in general, and induction motors in particular, temperature limits is a key factor affecting the efficiency of the overall design. Since conventional loading of induction motors is often expensive, the estimation of temperature rise by tools of mathematical modelling and computational experiments becomes increasingly important. In the present paper we develop and validate experimentally a model accounting for losses and describing thermal phenomena in induction motors. The developed model has been implemented in FEMLAB, and has been applied to predict temperature rise in totally enclosed fan-cooled induction motors. Comparisons with experimental results obtained with a 1.5 kW standard squirrel-cage induction motor show the effectiveness of the developed model in predicting temperature rise for a range of operating conditions, in particular for different frequencies and voltages. Finally, a SIMULINK-based control loop has been developed by using the thermal model as an input. © 2003 Elsevier Science Ltd. All rights reserved. (23 refs.)

Abstract: Silicon carbide bipolar junction transistors were fabricated in the study reported here. Three-dimensional thermal simulations were conducted for the SiC BJTs using FEMLAB. Thermal images of a device under operation were also recorded using an infrared camera. Both the simulations and the measurement show a significant temperature increase in the vicinity of the device when operated at high power densities, thus causing the decrease in the DC current gain. The junction temperature extracted during self-heating was approximately 154 °C at a power dissipation of 5.5 W, using the assumption that the current gain only depends on the temperature. The simulation results show a junction temperature of 157 °C at the same power level. Long-term stability tests over 80 hours were also performed at elevated temperatures, and a 10% decrease in the current gain was observed. (4 refs.)

Finite element model of magnetoconvection of a ferrofluid
Snyder, Suzanne M. (Department of Chemical Engineering, University of Washington, Box 351750); Cader, Tahir; Finlayson, Bruce A. Source: Journal of Magnetism and Magnetic Materials, v 262, n 2, June, 2003, p 269-279

Publisher: Elsevier  
  
Abstract: Combined natural and magnetic convective heat transfer through a ferrofluid in a cubic enclosure is simulated numerically. The momentum equation includes a magnetic term that arises when a magnetic fluid is in the presence of a magnetic field gradient and a temperature gradient. In order to validate the theory, the wall temperature isotherms and Nusselt numbers are compared to experimental work of Sawada et al. (Int. J. Appl. Electromagn. Mater. 4 (1994) 329). Results are obtained using standard computational fluid dynamics codes, with modifications to account for the Langevin factor when needed. The CFD code FIDAP uses the finite element method, sometimes with a user-defined subroutine. The CFD code FEMLAB uses the finite element method with a user-supplied body force. © 2003 Elsevier Science B.V. All rights reserved. (12 refs.)

Abstract: The combined MatLab toolboxes FemLab and Simulink are evaluated as solvers for HVAC problems based on partial differential equations (PDEs). The FemLab software is designed to simulate systems of coupled PDEs, 1-D, 2-D or 3-D, nonlinear and time dependent. In order to show how the program works, a complete code for solving a 2-D steady state heat transfer problem and the results are given. A validation study of a 2-D dynamic airflow problem, modeled using Navier Stokes and buoyancy is shown. All results show a good agreement with measurements. The use of Simulink is shortly discussed. Further advanced models include: a convective airflow around a convector, a thermal bridge model in FemLab connected to a room model and Pl controller in Simulink and an indoor airflow model in FemLab connected to an on/off controller in Simulink. At the conclusion the applications and the possible benefits for scientists, engineers and designers are discussed. (7 refs.)

Abstract: A two-dimensional dynamic model for bioleaching of secondary copper minerals from a pile has been developed. In the model, aeration of the pile is considered to be due to natural convection caused by the density gradient in the air within the bed. The rate of sulphide mineral dissolution is modelled according to the unreacted core model. The transport of ferric ions from the particle surface to the reaction zone is calculated considering film diffusion, diffusion within the particle and reaction kinetics. The rate of oxidation of the ferrous ion by bacteria attached to the ore surface is modelled using the Michaelis-Menten relationship. The influences of temperature, dissolved ferric iron and dissolved oxygen in the leaching solution are considered in the kinetic formulation. The set of partial differential equations is solved using the FEMLAB [registered trademark] software. The model was used to study the influence of process variables on copper recovery in the bed with time. This model is a useful tool to aid the design and optimisation of industrial operations. © 2003 Elsevier B.V. All rights reserved. (10 refs.)

Abstract: The design of a hierarchical controller using FEMLAB was discussed. The real-time optimal control problem included the computation of the optimal trajectory prediction and tracking of the optimal trajectory. The subproblems were solved in upper and lower level. The upper level included determination of the optimal trajectory and the time-consuming calculations.

  Influence of shed parameters on the aging performance of silicone rubber insulators in salt-fog
El-Hag, Ayman H. (Dept. of Elec. and Comp. Engineering, University of Waterloo); Jayaram, Shesha H.; Cherney, Edward A. Source: IEEE Transactions on Dielectrics and Electrical Insulation, v 10, n 4, August, 2003, p 655-664

Abstract: The paper presents the results of a study on the effect of shed design on the aging performance of silicone rubber (SIR) insulators in salt-fog. The experiments on a single shed design at 35 V/mm average stress and 0.25 S/m salt-fog conductivity level are reported. Shed diameter, location and inclination angle are the parameters investigated in the study. The low frequency harmonics of the leakage current, early aging period, equivalent salt deposit density (ESDD), and physical damage are used to evaluate the aging performance of various designs. Insulators having sheds with 100 mm diameter show a better performance than those having 80, 60 and 40 mm diameter sheds. The inclination angle of the sheds is shown to have a significant effect in reducing the leakage current to a very low value but simulation results using FEMLAB [registered trademark] show that a steep inclination angle results in field enhancement beneath the shed that may lead to corona damage of the shed. A cup shaped design for the shed is shown to have a low leakage current level and a low field enhancement beneath the shed. (18 refs.)
