Numerically Generated g-functions for Ground Coupled Heat Pump Applications

J. Acuna[1], M. Fossa[2], P. Monzó[1]
[1]KTH Energy Technology, Stockholm, Sweden
[2]Dime, University of Genova, Genova, Italy

Ground-coupled heat pumps (GCHP) are successfully installed since at about 20 years in many countries to fulfill space conditioning requirements in building applications. In most cases the heat pump is connected to a system of vertical ground heat exchangers (as illustrated in Figure 1) ... En savoir plus

Analysis of Asphalt Solar Collectors Using a Finite Element Approach

G. Guldentops [1], C. Vuye [2], S. Arimilli [2],
[1] Department of Civil Engineering, Worcester Polytechnic Institute, Worcester, USA
[2] Construction Department, University of Antwerp, Antwerp, Belgium

Current trends of research aims at the reduction of conventional fossil fuel consumption so as to mitigate anthropogenic global warming and thus to combat with the climate change. This can be done by shifting to more efficient, alternate, non-conventional and environmental friendly ... En savoir plus

Solving PDEs with Spatial & Time Varying Coefficients: Dirac Wave Function Passes Through EM Wave

A. J. Kalinowski¹
¹Consultant

The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψn n=1…4. This wave function describes the behavior of fermion type particles. The effect of a ... En savoir plus

Modeling a Novel Shallow Ground Heat Exchanger

M. Bottarelli[1], M. Bortoloni[1]
[1]Università degli Studi di Ferrara, Dipartimento di Architettura, Ferrara, Italia

Ground Heat Exchangers (GHXs) are rarely installed horizontally in linked ground source heat pumps used for space conditioning, because their energetic performance is lower than in the vertical solution. However, the horizontal one holds several advantages: it is easy to carry out and ... En savoir plus

On the Geometric Nonlinearity Effects of Polymeric Plates on Structural Performance

K. Vakkund[1], R. C. Thiagarajan[1]
[1]ATOA Scientific Technologies Pvt. Ltd., Bengaluru, Karnataka, India

Polymer sheets are widely used for glazing and roofing structural applications. The primary design requirements of these polymeric sheets are to resist uniformly distributed wind loading. Conventional building materials such as steel and glass plates are relative stiffer compared to ... En savoir plus

Dr.
Liquid Metal Metallurgy and Solidification department
Ugitech’s Research Center, Ugine, France

Dr. Christian Deville-Cavellin is a Research Engineer at Ugitech's Research Center, since 1995. Ugitech, member of the Schmoltz & Bickenbach group, is a stainless steel, long products producer. C. Deville-Cavellin is responsible for all research topics related to liquid metal ... En savoir plus

The Acoustic Behavior of a Loudspeaker Mounted on Different Types of BIW (Body-in-white) Frames

Niranjan Ambati [1], F. Malbos [2], Michal Bogdanski [3], Michael Strauss [3],
[1] Harman International Private Limited, Bangalore, Karnataka, India
[2] Harman France SNC, France
[3] Harman Becker Automotive Systems, Germany

For automotive applications, simulations are used to optimize the position and orientation of a subwoofer (loudspeaker) in a very constrained space to get the best acoustic performances. One solution is to use particular part of the BIW volume as the subwoofer enclosure. The acoustical ... En savoir plus

Rapid Prototyping of Biosensing Surface Plasmon Resonance Devices using COMSOL & Matlab software

J.J. Dubowski[1], and D.Carrier[1]
[1]Department of Electrical and Computer Engineering, Université de Sherbrooke, Quebec, Canada

We present a Finite Element Method simulation procedure that allows rapid development of prototype devices comprising novel self-referenced interference SPR (surface plasmon resonance) biosensing microstructures. The procedure takes advantage of COMSOL Multiphysics and MATLAB software ... En savoir plus

Simulation of Topology Optimized Electrothermal Microgrippers

O. Sardan[1], D. Petersen[1], O. Sigmund[2], and P. Boggild[1]
[1]DTU Nanotech, Denmark
[2]DTU Mechanical Engineering, Denmark

In this work, electrothermal microgrippers designed using topology optimization are modeled. The microgrippers are composed of two 5 μm-thick polysilicon actuators facing each other. The gap between the actuators are 2 μm in the initial state and the microgrippers are able to both fully ... En savoir plus

Melting and solidification behavior of PCM embedded in metal foam

Mohamed Moussa EL IDI¹, Mustapha KARKRI¹
¹Université Paris Est, CERTES.

In this paper, a numerical study is conducted on the melting and solidification process of metal foam/paraffin wax with cyclic heating and cooling. A mathematical model based on the Brinkman-Frochheimer extended Darcy equation and the local thermal non-equilibrium model (LTNE) is ... En savoir plus
