Numerical Modeling of Power Reactors' Fuel Bundles

R. Schmidt[1], T. Yousefi[2], B. Farahbaksh[2], M. Z. Saghir[2]
[1]University of Louisiana at Lafayette, Lafayette, LA, USA
[2]Ryerson University, Toronto, ON, Canada

Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the ... Mehr lesen

Study of the CO2 Transfer Rate in a Reacting Flow for the Refined Sodium ...

Study of the CO₂ Transfer Rate in a Reacting Flow for the Refined Sodium Bicarbonate Production Process

[1]Université Libre de Bruxelles, Brussels, Belgium
[2]Solvay S.A., Brussels, Belgium

This work deals with the quantification of the CO2 transfer rate from a bubble to the surrounding liquid in a bubble column. A model is successfully developed using COMSOL Multiphysics. The validated model is used to study the enhancement influence of chemical reactions on the transfer ... Mehr lesen

FEM Simulation for ‘Pulse-Echo’ Performances of an Ultrasound Imaging Linear Probe

L. Spicci[1]
[1]Esaote SpA, Florence, Italy

Pulse-echo FEM simulation is seldom found in literature for ultrasound imaging array probes, since the complete modeling of such device is extremely complicated. Nevertheless, the 2D FEM described in the present work was successful, thanks to the following design procedure (see figure): ... Mehr lesen

Newtonian and Non-Newtonian Blood Flow over a Backward-Facing Step: Steady-State Simulation

M.W. Siebert[1], and P.S. Fodor[1]
[1]Physics Department, Cleveland State University, Cleveland, Ohio, USA

In this work, the fluid flow over a 2D backward-facing step is analyzed in order to provide a case study for the use of different models for the blood dynamic viscosity in COMSOL Multiphysics. Three non-Newtonian models, as well as the Newtonian model are used to study the shear stresses ... Mehr lesen

Study of ER Non-equilibrium Behavior with COMSOL

L. Zhou
Fudan University, Shanghai, China

COMSOL Multiphysics is a powerful tool in theoretical study. Lei Zhou, Jiping Huang and other professors in Physics Department, Fudan University have achieved some exciting results of soft, tunable metamaterials. We use it to study non-equilibrium behavior of rhoeological (ER) fluids and ... Mehr lesen

Fluid Dynamics Modeling of an Industrial Wet Chemical Process Bath for the Si-Solar Cell Production

[1] Fraunhofer Institut for Solar Energy Systems ISE, Freiburg, Germany
[2] Singulus Technology AG, Fürstenfeldbruck, Germany

Silicon solar cells are produced in a series of different process steps in which wet-chemical etching and rinsing steps have a considerable influence on the quality of the wafers. Etching baths are used for surface structuring or intended etch back. Examples therefore are texturing, ... Mehr lesen

Numerical and Experimental Analysis of Natural and Mixed Convection Heat Transfer for Vertically Arranged DIMM

G. Petrone, and G. Cammarata
University of Catania, Catania, Italy

It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... Mehr lesen

Simulation of Chromatographic Band Transport

B. Bunner , A. Kromidas , M. Kele , and U. Neue
Waters Corp, Milford, MA, USA

High-Performance Liquid Chromatography (HPLC) is a standard method in the pharmaceutical industry for the separation and identification of chemical compounds. Modeling of band transport, or band broadening phenomena, can provide tremendous insight into problems of chromatography that ... Mehr lesen

Using Temperature Signals to Estimate Geometry Parameters in Fractured Geothermal Reservoirs

F. Maier[1], P. Oberdorfer[1], I. Kocabas[2], I. Ghergut[1], M. Sauter[1]
[1]Dpt. Applied Geology, Center of Geosciences, Georg-August-University, Göttingen, Germany
[2]Petroleum and Natural Gas Engineering Department Batman, Batman University, Batman, Turkey

We compare the output of 2D single fracture models as well as analytical solutions of the problem. The temperature signal is evaluated with the heat transfer mode while the flow field is assumed to exhibit Darcy flow everywhere. The problem is time-dependent so we have to take into ... Mehr lesen

Simulation of the Turbulent Flow in HEV Static Mixers : Mixing of Ethanol with Gasoline

A. Eissa[1]
[1]Department of Chemical Engineering, Cairo University, Giza, Egypt

Mixing is a typical unit operation that occurs almost in all chemical industries. Static – alternatively termed motionless – mixers are being widely used due to their low power consumption, low capital investment, minimal maintenance costs and versatility. The traditional helical mixing ... Mehr lesen
