Modeling Interface Response in Cellular Adhesion

G. Megali[1], D. Pellicanò[1], M. Cacciola[1], F. Calarco[1], D. De Carlo[1], F. Laganà[1], and F.C. Morabito[1]

[1]DIMET Department, Faculty of Engineering, University “Mediterranea” of Reggio Calabria, Reggio Calabria, Italy

Constitutive properties of living cells are able to withstand physiological environment as well as mechanical stimuli occurring within and outside the body. We examined fluid flow and Neo-Hookean deformation related to the rolling effect. A mechanical model to describe the cellular ... Read More

Modelling and Experimental Validation Possibilities of Heat Transfer Room Model

M. Zalesak, and V. Gerlich
Tomas Bata University in Zlin, Zlin, Czech Republic

The study presents first authors experience with COMSOL Multiphysics environment used as a possible modeling tool of thermal building behavior. The idea of the project was to gain thermal response to changed boundary conditions with the application of COMSOL environment as a modeling ... Read More

Designing a Smart Skin with Fractal Geometry

S. Ni, C. Yang Koh, S. Kooi, and E. Thomas
Institute for Soldier Nanotechnologies
Dept. of Materials Science and Eng.
Cambridge, MA

Recently, the concepts of fractal geometry have been introduced into electromagnetic and plasmonic metamaterials. With their self-similarity, structures based on fractal geometry should exhibit multi-band character with high Q factors due to the scaling law. However, there exist few ... Read More

Porous Media Based Model for Deep-Fat Vacuum Frying Potato Chips

A. Warning, A. K. Datta, A. Dhall, and D. Mitrea
Department of Biological and Environmental Engineering
Cornell University
Ithaca, NY

A multiphase porous media model involving heat and mass transfer within a potato chip was implemented in COMSOL 3.5a. The diffusive flux in oil and liquid water was modeled from capillary driven flow while the gas phase was modeled using binary diffusion. A non-equilibrium water ... Read More

Assessment of Spatial Variably Saturated Flow by Irrigation Moisture Sensors in 2-Dimensions using the COMSOL Multiphysics 4.1

A. Boluwade, and C. A. Madramootoo
Bioresources Engineering, McGill University
Ste. Anne De Bellevue, QC

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which ... Read More

Using Comsol 4.1 to Build a Transient Model of a Drift Tube Ion Mobility Spectrometer with Improved Performance

J. Langejürgen, P. Cochems, U. Günay, M. Allers, and S. Zimmermann
Leibniz University Hannover
Hannover, Germany

An Ion Mobility Spectrometer is a device to analyze different components of a gas mixture. A feature of this technology is the ultra-low detection limit which can be obtained for most trace gases. Due to a limited resolution which is needed to differ between different components an ... Read More

Modeling of Limestone Calcination Using Joule Heating

R. Kancharla, and M. Ramakrishna
Padmasri Dr. B.V.Raju Institute of Technology
Medak Dist, AP, India

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in ... Read More

Simulation Analysis of Acoustic Radiation Force under Ultrasound Exposure and Effect to Microbubbles in Flow

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 ... Read More

Acoustic-Structure Interaction Modeling of Piezoelectric Transducer in Fluid Medium

V.M. Acosta[1], E. Riera[1], G. Rodriguez[1], A. Pinto[1], A. Cardoni[2], J.A. Gallego-Juárez[1]
[1]Power Ultrasonics Group, CSIC, Serrano, Madrid, Spain
[2]Pusonics, Arganda del Rey, Madrid, Spain

This work describes the design methodology and development of piezoelectric transducers for applications in fluids with COMSOL_Multiphysics. In these linear models for the acoustic-structure interaction approximate numerical solutions have been obtained. In order to perform the ... Read More
