COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity

A. Mario-Cesar Suarez[1], and V. Fernando Samaniego[2]

[1]Faculty of Sciences, Michoacan University, Morelia, Mich., Mexico
[2]Faculty of Engineering, National University of Mexico, Mexico City, Mexico

The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... En savoir plus

Design and Simulation of MEMS based PZT energy generator.

A. Deshpande[1]
[1]B.V.Bhoomaraddi College of Engineerring & Technology, Hubli, Karnataka, India

At present, a great deal of research effort has been directed to find eco-friendly and renewable sources of energy. With the rising costs of crude oil and petroleum, along with the derogatory effects that they pose to the environment, this sort of approach is of utmost importance. This ... En savoir plus

Adaptive Control of Simulated Moving Bed Plants Using Comsol’s Simulink Interface

M. Fütterer
Institut für Automatisierungstechnik, Otto-von-Guericke Universität, Magdeburg, Germany

Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to ... En savoir plus

Coupled Electric-Thermal-Fluid Analysis of High Voltage Bushing

G. Eriksson[1]
[1]ABB, Corporate Research, Västerås, Sweden

Modern power transmission systems are in general designed to operate at high voltages in order to reduce resistive losses generated by high currents. This, however, tends to increase the risk for dielectric breakdown or flashovers if the equipment is not properly designed to withstand ... En savoir plus

Effect of Magnetic Field on MR-Fluid in Ball End Magnetorheological Finishing

H. Garg[1], V. S. Negi[1], A. S. Kharola[1], R. Sharma[1]
[1]CSIR - Central Scientific Instruments Organization, Chandigarh, India

Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... En savoir plus

CFD Based Optimisation of a Laboratory Scale Silo

A. Egedy [1], A. Rado [1],
[1] University of Pannonia, Faculty of Engineering, Veszprém, Hungary

The flow simulation of solid, particulate materials is still challenging, even though estimations show that three-quarters of products and raw materials are present as granules form in the industry. We can think of grain in the agriculture, raw materials of the glass industry, granulated ... En savoir plus

Optimization of Artificial Diffusion Stabilization Techniques and Corresponding Mesh Density Distribution in Drift Dominated Transport of Diluted Species

J. Jadidian[1], M. Zahn[1], N. Lavesson[2], O. Widlund[2], K. Borg[2]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA
[2]ABB Corporate Research, Västerås, Sweden

This paper presents an optimized combination of artificial diffusion techniques to stabilize a drift dominated streamer discharge model which includes COMSOL Multiphysics’ Transport of Diluted Species modules for positive ion, negative ion, and electron charge densities, coupled through ...

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... En savoir plus

Simulation of a 3D Flow-Focusing Capillary-Based Droplet Generator

D. Conchouso[1], E. Al Rawashdeh[1], A. Arevalo[1], D. Castro[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

This paper presents the multiphase 2D axisymmetric simulation of a three-dimensional flow-focusing microfluidic droplet generator using the laminar two phase flow, phase field interface in COMSOL Multiphysics®. The performance of the device is characterized at different flow conditions. ... En savoir plus

Multiphase Laminar Flow with More Than Two Phases

W. T. Vetterling [1],
[1] Zink Imaging, Inc., Billerica, MA, USA

Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... En savoir plus
