Blistering of Industrial Floor on Concrete Substrate: the Role of the Air Overpressure

S.V. Aher[2], P. Devillers[1], G. Fau[3], B. Tranain[3], and C. Buisson[1]
[1]Centre des Matériaux de Grande Diffusion, Ecole des Mines d’Alès, Alès cedex, France
[2]Indian Institute of Technology Kanpur, Kalyanpur, Kanpur, Uttar Pradesh, India
[3]Centre Scientifique et Technique du Bâtiment, France

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... Read More

Thermal and Laminar-Fluidic Workbench for a metric Portion of a Gun

M. Brun
Nexter Systems, Versailles, France

Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a ... Read More

Microwave Drying of Cellular Ceramic Substrates: A Conjugate Modeling Approach to Understand Surface Moisture Migration

Corning, Inc.
Painted Post, NY

Microwave drying processes are critical components in the manufacture of cellular ceramic substrates and filters. The objective of this study is to develop a comprehensive model at a small scale and include all the possible physics that are important during microwave drying processes. ... Read More

Constructing COMSOL Models of a Bacteriological Fuel Cell

R. Coker[1], J. Mansell[1]
[1]NASA - Marshall Space Flight Center, Huntsville, AL, USA

We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated ... Read More

Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

C. Wang[1], Y. Song[1]
[1]Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL ... Read More

Application for Ultrasensitive Biosensing by Nanodevise

[1]Takatoki YAMAMOTO

Tokyo Institute of Technology, Yokohama, Kanagawa, Japan[1]

It is possible to obtain novel functions using nano-scaled structures and related physics that are impossible to be realized by conventional macro-scale technology. Thus, we are trying to understand the physics dominated by nanostructure and to develop the biosensing applications. Here, ... Read More

Chemical Reaction under Highly Precise Microwave Irradiation

Satoshi Fujii et al.[1]

[1]Chiba University, Chiba, Chiba, Japan

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... Read More

Computational Multiphysics to Optimize Humidification Chamber for a Novel PEM Fuel Cell Power System Used in Automobile Application new

M. Raja[1]
[1]Tata Motors, Bengaluru, Karnataka, India

Proton Exchange Membrane (PEM) fuel cells are quickly becoming an attractive technology due to their ability to meet increasing energy demands in a cleaner, more efficient way compared to existing methods. A fuel cell is an electrochemical device which converts the chemical energy of a ... Read More

Effect of Area of the Reaction Surface on the Capture Efficiency of Immunosensors

D. Rath [1], S. Panda [1],
[1] Indian Institute of Technology, Kanpur, India

With the progress of immunosensing technology, the detection of diseases at early stages is feasible using surface based heterogeneous immunosensors [1]. Literature contains few reports where it is verified that reaction spot of smaller size leads to high fractional occupancy of targets, ... Read More
