Comparison between COMSOL and RFSP-IST for a 2-D Benchmark Problem

G. Gomes
Atomic Energy of Canada Limited, Mississauga, Ontario, Canada

RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For ... En savoir plus

Analysis of Heat, Mass Transport, and Momentum Transport Effects in Complex Catalyst Shapes for Gas-Phase Heterogeneous Reactions Using COMSOL Multiphysics

A. Nagaraj[1], and P. Mills[2]

[1]Department of Electrical Engineering and Computer Science, Texas A&M University, Kingsville, TX, USA
[2]Department of Chemical and Natural Gas Engineering, Texas A&M University, Kingsville, TX, USA

The global demand for sulfuric acid has been forecast to grow at an average of 2.6% per year from 2005 – 2010. The primary objective of this work is to analyze the performance of various heterogeneous catalyst shapes that have been proposed for the oxidation of SO2 to SO3 used in the ... En savoir plus

Sensitivity Estimation of Permanent Magnet Flowmeter

V. Sharma[1], S. K. Dash[1], G. Vijaykumar[1], B. K. Nashine[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus

Thermal Model and Control of Metal-Organic Chemical Vapor Deposition Process

J. L. Ebert [1], S. Ghosal [1], N. Acharya [1]
[1] SC Solutions, Inc., Sunnyvale, CA, USA

Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... En savoir plus

Analysis of Coupled Dynamics of Molten Salt Reactors

V. Di Marcello, A. Cammi, and L. Luzzi
Department of Energy, Nuclear Engineering Division (CeSNEF), Politecnico di Milano, Milano, Italy

This paper presents a preliminary analysis of the coupled thermo-hydrodynamics and neutronics of circulating nuclear fuel systems in a nuclear reactor that adopts a molten salt mixture. This flows up through channels in a graphite moderated core and plays the role of both heat generator ... En savoir plus

Thermal study of wafer cooling and heat resistance fitting

Hervé ROUCH¹, Fabrice BOILOT¹
¹INOPRO IAO, Villard De Lans, France

Temperature management and homogeneity on wafers has always an important effect on production in all microelectronics fields. The heat resistance of every mechanical contact, not only clamping, may decrease the precision of temperature regulation. But they also increase the difficulties ... En savoir plus

Modeling the Catalytic Conversion of Steel Mill Gases Using the Example of Methanol Synthesis

S. Schlüter [1], T. Hennig [1],
[1] Fraunhofer UMSICHT, Oberhausen, Germany

The conversion of steel mill off-gases to base chemicals is a promising perspective to improve the financial return of steelmaking in Europe and fight CO2 emissions. In the Carbon2Chem® joint research project, mathematical models are developed to simulate operation scenarios of cross ... En savoir plus

Multi-Frequency Design of an Optimized Microwave Cavity for Plastic Recycling Applications

L. Royo[1], A. Frisa[1], T. García[1], J. Consejo[1]
[1]Fundación CIRCE, Spain

Microwave heating has been used in industry because of its pollution free and rapid heating technique [1]. It consists of an electromagnetic wave that passes through a media with a frequency between 300 MHz and 300 GHz [2] to generate heat in the system. The purpose of the current work ... En savoir plus

Modeling of Mixing-Sensitive Pharmaceutical Drug Substance Processes in Batch Reactors

F. Akpinar [1], B. Cohen [1], J. Tabora [1], A. Glace [1], K. Lauser [1], F. Lora Gonzalez [1], J. Albrecht [1],
[1] Bristol-Myers Squibb, New Brunswick, NJ, USA

Manufacturing of pharmaceutical drug substances involves chemical unit operations that are dependent on effective mixing, particularly reactions and crystallizations. Poor mixing can cause uneven distribution of chemical species in stirred tanks, leading to impurity formation and ... En savoir plus

Analysis of Flow in a Microfluidic Device: Pressure Drop, RTD and Mixing

A. Kulkarni[1]
[1]NCL, Pune, Maharashtra, India

Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby ... En savoir plus
