Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software

C. Belavý[1], G. Hulkó[1], S. Lipár[1], B. Barbolyas[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... En savoir plus

Simulation of the Turbulent Flow in HEV Static Mixers : Mixing of Ethanol with Gasoline

A. Eissa[1]
[1]Department of Chemical Engineering, Cairo University, Giza, Egypt

Mixing is a typical unit operation that occurs almost in all chemical industries. Static – alternatively termed motionless – mixers are being widely used due to their low power consumption, low capital investment, minimal maintenance costs and versatility. The traditional helical mixing ... En savoir plus

The Influence of Sensor Technology on the Performance of Acoustic Leak Detection for Water Networks

S. Perrier¹, V. Burtea¹, B. Robertson¹, M. Moslemi¹, J. Butterfiled¹
¹Echologics, Toronto, ON, Canada

As water networks around the world age, leakage and water main breaks are becoming an increasing problem. Leakage rates of 10-30% are typical in North America, and most cities suffer from hundreds (or thousands) of water main breaks every year. Echologics has developed the EchoShore ... En savoir plus

Multiphysics Modelling in the Electromagnetic Levitation and Melting of Liquid Metals

A. A. Roy, V. Bojarevics, and K. Pericleous
University of Greenwich
London, UK

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation ... En savoir plus

COMSOL Multiphysics is offering an important alternative to home codes for modeling and simulation of complex problems with including coupled effects on heat and mass transfer. The present work focuses on low Prandtl number fluid melts subject to symmetry breaking and transition to ... En savoir plus

Numerical and Experimental Analysis of Natural and Mixed Convection Heat Transfer for Vertically Arranged DIMM

G. Petrone, and G. Cammarata
University of Catania, Catania, Italy

It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... En savoir plus

Numerical Modeling of Power Reactors' Fuel Bundles

R. Schmidt[1], T. Yousefi[2], B. Farahbaksh[2], M. Z. Saghir[2]
[1]University of Louisiana at Lafayette, Lafayette, LA, USA
[2]Ryerson University, Toronto, ON, Canada

Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the ... En savoir plus

Mixing and Residence Time Distribution Studies in Microchannels with Floor Herringbone Structures

A. Cantu-Perez, S. Ping Kee, and A. Gavriilidis
University College London, Department of Chemical Engineering, Torrington Place, London, UK

The mixing characteristics and residence time distributions (RTDs) of a staggered herringbone microchannel have been investigated numerically by COMSOL Multiphysics and by particle tracking algorithms that incorporate diffusion via a random walk. All simulations were validated with ... En savoir plus
