A Theoretical Model for the Control of Color Degradation and Microbial Spoilage Occurring in Food Convective Drying

S. Curcio[1], M. Aversa[1]
[1]University of Calabria, Department of Engineering Modeling, Rende, Cosenza, Italy

The aim of this work was the development of a predictive model aimed at identifying a proper control strategy of food drying process. In particular, it was intended to determine the effect of operating conditions both on the color degradation, chosen as a reference quality parameter, and ... En savoir plus

Development of Hybrid "Fluid Jet / Float" Polishing Process

Anthony Beaucamp[1]
Y. Namba[2]

[1]Zeeko LTD, Coalville, Leicestershire, UK
[2]Chubu University, Kasugai, Aichi, Japan

On one hand, the "float polishing" process consists of a tin lap having many concentric grooves, cut from a flat by single point diamond turning. This lap is rotated above a hydrostatic bearing spindle of high rigidity, damping and rotational accuracy. The optical surface thus floats ... En savoir plus

Simulation of MEMS based Flexible Flow Sensor for Biomedical Application

D. Maji[1], C. P. Ravikumar[2], and S. Das[1]
[1]School of Medical Science and Technology, Indian Institute of Technology, Kharagpur, West Bengal, India
[2]Texas Instruments (India) Pvt. Ltd., Bangalore, India

Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood interacts with vessel wall mechanically and chemically which modulates the plaque formation in blood vessel leading to coronary artery ... En savoir plus

Progress in Numerical Simulation of HIIPER Space Propulsion Device

P. Keutelian[1], A. Krishnamurthy[1], G. Chen[1], B. Ulmen[1], G.H. Miley[1]
[1]University of Illinois at Urbana-Champaign, Champaign, IL, USA

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... En savoir plus

Convergence Rates For Models With Coupled 1D / 2D Subdomains

A. Bradji[1], E. Holzbecher[2], and M.S. Litz[2]
[1]Department of Mathematics, University of Annaba, Algeria
[2]Georg-August Universität Göttingen, Germany

It is well known that the convergence rate of a numerical model is significantly reduced, when the genuine character of the setting with differential equation and boundary condition is not given anymore. Here we examine the decrease of convergence order for models using COMSOL in which ... En savoir plus

Tertiary Current Distributions on the Wafer in a Plating Cell

L. Tong[1]
[1]Keisoku Engineering System Co., Tokyo, Japan

The tertiary current distributions on the wafer in a plating cell are studied in this work. An acid copper sulfate electrolyte composed of CuSO4/5H2O of 2.4 g/L and H2SO4 of 90 g/L is taken into account for copper deposition on the wafer. The solution of shear-plate agitating fluid ...

Simulation of Brine Reflux and Geothermal Circulation in Large Carbonate Platforms: An Attempt to Predict Dolomite Geo-Bodies

M. Pal, and C. Taberner
Shell International Exploration and Production B.V.
Rijswijk, The Netherlands

Significant volumes of the worlds proved reserves are in dolostone reservoirs. Scope for recovery and success/upside of new exploration plays depend on the chances of encountering dolostone reservoirs with good reservoir properties. Although dolostones make excellent reservoirs in ... En savoir plus

Transport Phenomena and Shrinkage Modeling During Convective Drying of Vegetables

S. Curcio[1] and M. Aversa[1]
[1]Department of Engineering Modeling, University of Calabria, Arcavacata di Rende, CS, Italy

The aim of the present work is the formulation of a theoretical model describing the transport phenomena involved in food drying process. The attention has been focused on the simultaneous transfer of momentum, heat and mass occurring in a convective drier where hot dry air flows, in ... En savoir plus

Melt Homogenization Improvement By Optimizing the Rotation Profile

J. Petit [1], V. Tabouret [1], B. Viana [2],
[1] ONERA, Chatillon, France
[2] IRCP/CNRS, Paris, France

During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non ... En savoir plus

Thermal Hydraulic Study for Heavy Liquid Metal Flows using COMSOL Multiphysics

K. T. Sandeep[1], S. Sahu[1], V. C. Chaudhari[1], R. P. Bhattacharyay[1], E. R. Kumar[1]
[1]Institute for Plasma Research, Gandhinagar, Gujarat, India

Liquid metals are the extensively used as coolants in nuclear reactors.However, the heat transfer mechanism differs significantly in low Prandtl number heavy liquid metals (HLM’s) than those observed in common fluids. It is crucial to have the accurate heat transfer correlation for the ... En savoir plus
