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

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

[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

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

Design, Fabrication and Simulation of Microchannel Network for MEMS

V. Jain[1], A. K. Sharma[2], P. Kumar[2]
[1]Thapar University, Patiala, Punjab, India
[2]Indian Institute of Technology Roorkee, Roorkee, Uttar Pradesh, India

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the ... En savoir plus

Investigation of Reverse ElectroDialysis Units by Multi-Physical Modelling

L. Gurreri [1], F. Santoro [1], G. Battaglia [1], A. Cipollina [1], A. Tamburini [1], G. Micale [1], M. Ciofalo [1],
[1] Dipartimento di Ingegneria Chimica, Gestionale, Informatica, Meccanica (DICGIM), Università degli Studi di Palermo (UNIPA), Palermo, Italy

Salinity gradient represents an interesting renewable energy source. Reverse ElectroDialysis (RED) is an ion exchange membrane-based process that convert directly the salinity gradient energy into electric current. Thereby, two solutions at different concentrations are fed into two ... En savoir plus

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... En savoir plus

The Fast Model for Ionic Wind Simulation

A. Samusenko[1], Yu. Stishkov[1], P. Zhidkova[1]
[1]Saint Petersburg State University, Research and Educational Center “Electrophysics”, St Petersburg, Russia

Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... En savoir plus

Numerical Simulation of Concentration Polarization to Estimate Gypsum and Calcium Carbonate Scaling on Membrane Surfaces

A. Santafé-Moros[1], J.M. Gozálvez-Zafrilla[1]
[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain

This paper shows a model to estimate the scaling parameters for reverse osmosis membrane processes. The model takes into account the concentration polarization of ionic species in the membrane channel of spiral-wound modules and the effect of the spacers on the flow. The scaling ... En savoir plus

Numerical Aspects of the Implementation of Artificial Boundary Conditions for Laminar Fluid-Structure Interactions

C. Boeckle[1], P. Wittwer[1]
[1]University of Geneva, Geneva, Switzerland

We discuss the implementation of artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a finite domain for numerical purposes, artificial boundaries appear. We present an ... En savoir plus

Numerical Simulations Demonstrate Safe Vitrification and Warming of Embryos Using the Rapid-i™ Device

B.O.J. Johansson[1][2], Y.A. Tarakanov[1], H.J. Lehmann[2], and S.P. Apell[1]

[1]Department of Applied Physics, Chalmers University of Technology, Gothenburg, Sweden
[2]Vitrolife Sweden AB, Västra Frölunda, Sweden

During cryopreservation of human embryos, ice crystal formation in the embryos or in surrounding media may cause cryodamage to them and can be lethal. A strategy to avoid this is the vitrification procedure when the embryo and the surrounding medium undergo the transition to glassy state ... En savoir plus
