Design of an Anisokinetic Probe for Sampling Radioactive Particles from Ducts of Nuclear Facilities

P. Geraldini [1],
[1] Sogin Spa, Rome, Italy

The aim of this study is to design a new concept of shrouded probe that meets the ISO 2889 requirements and it is suitable for small-ducts installation. In order to reduce the construction costs they have been considered standard stainless steel welding fittings manufactured according to ... En savoir plus

Simulation of a Nozzle in a Borehole

E. Holzbecher [1], F. Sun [2],
[1] German University of Technology in Oman, Muscat, Oman, Germany
[2] Georg-August-Universität, Göttingen, Germany

In boreholes nozzles have to be found advantageous to increase the infiltration rate of water into the subsurface ground. Studies and practice in the field shows that the infiltration of water into permeable aquifers can be improved, if the flow in the borehole is modified. Due to the ... En savoir plus

Simulation of Chemotractant Gradients in Microfluidic Channels to Study Cell Migration Mechanism in Silico

P. Wallin[1], E. Bernson[1], J. Gold[1]
[1]Chalmers University of Technology, Applied Physics, Biological Physics, Gothenburg, Sweden

Cell migration of endothelial cells along gradients is an important process in vivo and an interesting target for cancer therapeutics. Microfluidics offer very powerful tools to study such migration processes in detail in the lab. In this study, we describe a model to simulate molecular ... En savoir plus

Air Flow Characteristics Inside an Industrial Wood Pallet Drying Kiln

A-G. Ghiaus, M-A. Istrate, and A-M. Georgescu
Technical University of Civil Egineering, Bucharest, Romania

Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in ... En savoir plus

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ...

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

Heat Loss Evaluation of an Experimental Set-up for Predicting the Initial Stage of the Boiling Curve for Water at low Pressure

K. T. Witte[1], F. Dammel[2], L. Schnabel[1], and P. Stephan[2]
[1]Fraunhofer Institut Solare Energiesysteme - Department of Thermal Systems and Buildings, Freiburg, Germany
[2]Technische Universität Darmstadt - Institute of Technical Thermodynamics, Darmstadt, Germany

In this paper heat losses and gains are assessed for a specific measuring set-up improving the validity of performance data to accurately predict the initial stage of a boiling curve. Simulation focus on achieving results predicting real measuring data of a plain surface structure. ... En savoir plus

Numerical Modeling of Falling Aluminum Particle Oxidation in Air

A. Davidy
Israel Military Industry, Ramat-Hasharon, Israel

Because of its high enthalpy of combustion, aluminum has been added to energetic materials. In this paper, a two dimension thermal model is developed and assessed to describe the interrelated processes of Aluminum particle oxidation by using the software COMSOL Multiphysics. The thermal ...

Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ...

High-Resolution FSI Modeling of a High-Aspect Ratio Involute Flow Channel in the HFIR at ORNL

A. I. Elzawawy [1], J. D. Freels [2], F. G. Curtis [2, 3],
[1] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA
[3] University of Tennessee, Knoxville, TN, USA

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid ... En savoir plus
