Benard-Rayleigh convection in thin ring layer

A. Fedotov¹, Y. Tsitavets¹, Y. Levy²
¹Belarusian State University, Minsk, Belarus
²HiLASE Centre, Prague, Czech Republic

Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... 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

A Numerical Investigation on Active Chilled Beams for Indoor Air Conditioning

G. Cammarata, and G. Petrone
Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... 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

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

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

Simulation of GMR in Granular C/Co Nanoparticles in Agarose

P. Hainke[1], D. Kappe[1], A. Hütten[1]
[1]Universität Bielefeld, Bielefeld, Germany

As the importance of nanoparticles is growing more and more, controlling and understanding the properties of nanoparticles became a focus of research. In this field Meyer at al. [1] are researching the GMR effect in granular gels to develop magnetoresistive sensors. The GMR in granular ... En savoir plus

Calibration of a Geothermal Energy Pile Model

R. Caulk[1], J. McCartney[2], E. Ghazanfari[1]
[1]University of Vermont, Burlington, VT, USA
[2]University of Colorado, Boulder, CO, USA

In this study, a model of in-situ geothermal energy piles was constructed using COMSOL Multiphysics® software. Geothermal energy piles serve two purposes, first to transfer building load into the subsurface, but also to extract thermal heat from surrounding soils. This is achieved using ... En savoir plus
