Heat Transfer and Phase Changex

Thermal Study of Valve Regulated Lead Acid Batteries and Electronics Chamber Used in Stand-Alone Street Lighting Applications

D. Groulx[1], J. Skaalum[1], T. Jamieson[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

This paper presents a study on the heat generation of Valve-Regulated Lead Acid (VRLA) batteries used in off-grid streetlighting applications from PoleCo, a Halifax based company. One goal of the project was to produce validated COMSOL® models of the enclosure that holds these VRLA ... Read More

A Single Particle Thermal Model for Lithium Ion Batteries

R. Painter[1], S. Berryhill[1], L. Sharpe[2], S. K. Hargrove[2]
[1]Department of Civil Engineering, Tennessee State University, Nashville, TN, USA
[2]Department of Mechanical Engineering, Tennessee State University, Nashville, TN, USA

COMSOL® "Single Particle Model for Lithium-Ion Batteries” (Model ID: 14527) is generalized to include an energy balance. This is accomplished by approximating the solution phase polarization as a function of current and temperature. The theoretical approach for this work is similar to ... Read More

Analysis of Heat Transfer in a Complex Three Dimensional Structure Fabricated by Additive Manufacturing

C. Settle[1], K. Hoshino[1]
[1]Biomedical Engineering Department, University of Connecticut, Storrs, CT, USA

The goal of this study was to create a three dimensionally designed biomedical device with multiple functionalities and analyze its simulated heat transfer. The device would be fabricated through additive manufacturing; specifically electron beam melting (EBM). EBM has a feature size ... Read More

Modeling of a Counter Flow Plate Fin Heat Exchanger

R. Jia[1], J. Hu[1], X. Xiong[2]
[1]Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA
[2]Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA

Plate fin heat exchangers are widely used for heat recovery or cooling purposes in many industries, such as cryogenics, aerospace and automobile industries. This paper developed a numerical model to simulate the heat transfer and fluid flow in a counter flow plate fin heat exchanger and ... Read More

Modeling Self-Potential Effects during Reservoir Stimulation in Enhanced Geothermal System

G. Perillo[1], A. Monetti[2], A. Troiano[2], M. G. Di Giuseppe[2], C. Troise[2], G. De Natale[2]
[1]University of Naples Parthenope, Naples, Italy
[2]INGV-Osservatorio Vesuviano, Naples, Italy

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from ... Read More

Thermal Battery Cell Modeling in a Spirally-Wound Geometry

G.Liebig[1], L. Komsiyska[1], P. Bise[1], H. Seeba[1], P. Bohn[2], S. Vasic [1]
[1]NEXT ENERGY, Oldenburg, Niedersachsen, Germany
[2]AUDI AG, Ingolstadt, Bayern, Germany

The characterization of Li-ion batteries is a relevant topic due to the recent developments in Electric Vehicles (EV’s) and Hybrid Electric Vehicles (HEV’s) applications. In order to manage these devices, accurate models are required. At NEXT ENERGY a two dimensional cell-level thermal ... Read More

Investigating the Performance of Mechanically Ventilated Double-Skin Facades with Solar Control Devices in the Main Cavity

C. G. Galante[1]
[1]Newtecnic Ltd, London, England, UK

The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to ... Read More

Heat Transfer in Borehole Heat Exchangers from Laminar to Turbulent Conditions

E. Holzbecher[1], H. Räuschel[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

Borehole heat exchangers (BHE) in connection with heat pumps and floor heating in many countries are becoming an alternative to conventional heating or cooling systems using fossil resources. We describe how 1D components for heat transport in pipes can be coupled with a 2D or 3D ... Read More

Heat Transfer Modeling of Power Cables in Tunnels

F. Boukrouche[1], C. Moreau[1], W. Frelin[1]
[1]EDF R&D, Moret-sur-Loing, France

Electric power, in cities or for power plant outflow, is most often transmitted through underground cables. Due to increased electricity demands power suppliers make large investments to house these cables in deep or shallow tunnels. The thermal environment is complex, with different ... Read More

Short-Term Behavior and Steady-State Value of BHE Thermal Resistance

S. Lazzari[1], A. Priarone[2],
[1]DIN, University of Bologna, Bologna, Italy
[2]DIME-TEC, University of Genova, Genova, Italy

The transient behavior of the thermal resistance of single and double U-tube borehole heat exchangers (BHEs) is investigated numerically by means of COMSOL Multiphysics® software with reference to the 2D cross section of usually employed BHEs. The study is performed in a dimensionless ... Read More
