Characterization of a Tonpilz Transducer and Performance Analysis for a MEMS-Transducer Array

V. Vadde, and B. Lakshmi G
PESIT

In this paper, we develop and analyze a standard piezoacoustic Tonpilz-transducer model for underwater acoustics in Comsol by addressing the attendant piezoelectric and pressure acoustic multiphysics phenomena. Transducer properties that are studied and characterized are the center ... En savoir plus

COMSOL Assistance For The Determination Of Pressure Drops In Complex Microfluidic Channels

J. Berthier, R. Renaudot, P. Dalle, G. Blanco-Gomez, F. Rivera, P. Caillat, and V. Agache
CEA-LETI, Grenoble, France

With the current trend towards always more complexity associated to more functionalities in biotechnological systems, it is required to know with accuracy the pressure drop in the circuitry of microfluidic systems. In general, a full three-dimensional calculation is not tractable due to ... En savoir plus

Multiphysics Modelling of Standing Column Well and Implementation of Heat Pumps Off-Loading Sequence

A. Nguyen[1], P. Pasquier[1], D. Marcotte[1]
[1] Department of Civil, Geological and Mining Engineering, École Polytechnique de Montréal, Montréal, QC, Canada

A fully coupled multiphysics model involving heat transfer and groundwater flow within a SCW and its surrounding ground was implemented in COMSOL Multiphysics 4.2a with MATLAB to simulate a 24-hour heating operation. The heat pumps were modeled using interpolation functions thereby ... En savoir plus

Simulation of Constant-Volume Droplet Generators for Parallelization Purposes

D. Conchouso [1], A. Arevalo [1], D. Castro [1], Y. Ying [1], I. G. Foulds [2]
[1] King Abdullah University of Science and Technology, Thuwal, Makkah, Saudi Arabia
[2] School of Engineering, University of British Columbia - Okanagan, Vancouver, BC, Canada

To maintain same droplet size across parallel devices, new break-up strategies based on geometry are been studied. In this work, we model a geometrically-set droplet generator, in which the droplet break-up occurs by a block and break mechanism. In other words when the disperse phase ... En savoir plus

Multiphysics Simulation of a Circular-Planar Anode-Supported Solid Oxide Fuel Cell

K. Daneshvar[1], A. Fantino[1], C. Cristiani[1], G. Dotelli[1], R. Pelosato[1], M. Santarelli[2]
[1]Politecnico di Milano, Dipartimento di Chimica, Materiali e Ingegneria Chimica “G. Natta”, Milano, Italy
[2]Politecnico di Torino, Dipartimento di Energetica, Torino, Italy

A 2D isothermal axisymmetric model of an anode-supported Solid Oxide Fuel Cell (SOFC) has been developed. Also a parametric analysis to find the effect of important parameters on the cell performance has been done. This simulation has been carried out at 1 atm and 1073 K. The PEN ... En savoir plus

Upgrading the HFIR Thermal-Hydraulic Legacy Code Using COMSOL

I.T. Bodey[1], R.V. Arimilli[1], and J.D. Freels [2]
[1]The University of Tennessee, Knoxville, TN, USA,
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

Modernization of the High Flux Isotope Reactor (HFIR) thermal-hydraulic (TH) design and safety analysis capability is an important step in preparation for the conversion of the HFIR core from a high enriched Uranium (HEU) fuel to a low enriched Uranium (LEU) fuel. Currently, an important ... En savoir plus

Exergy Analysis of a Water Heat Storage Tank

F. Dammel[1], J. Winterling[1], K. J. Langeheinecke[2], P. Stephan[3]
[1]Institute of Technical Thermodynamics, Technische Universität Darmstadt, Germany
[2]IAV, Gifhorn, Germany
[3]Institute of Technical Thermodynamics/Center of Smart Interfaces, Technische Universität, Darmstadt, Germany

A combined heat and power (CHP) plant generates both electricity and useful heat. A heat storage tank enables a decoupling of electricity and heat delivery. In this study a cylindrical hot water storage tank is considered. Charging, holding time and discharging are numerically simulated ... En savoir plus

An Extension of Lauwerier’s Solution for Heat Flow in Saturated Porous Media

S. Saeid[1] and F.B.J. Barends[2]
[1]Technical University of Delft, Delft, The Netherlands
[2]Deltares and TU-Delft, Delft, The Netherlands

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and ... En savoir plus

Water Quality Model for Brewster Lake

Z. Aljobeh[1], G. Argueta[1]
[1]Valparaiso University, Valparaiso, IN, USA

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the ... En savoir plus
