High Temperature Process Simulation

O. Geoffroy, and H. Rouch
INOPRO, Villard de Lans, France

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The ... En savoir plus

Investigations on Hydrodynamic in Stirred Vessels for Educational Purposes

A. Egedy, T. Varga, and T. Chován
University of Pannonia
Department of Process Engineering
Veszprém, Hungary

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research ... En savoir plus

Atmospheric Microwave Plasma

T. S. Marquardt [1], D. F. Shewamene [1], J. J. Swanson [1],
[1] Integrated Engineering, Minnesota State University, Mankato, MN, USA

Plasma gasification of biomass is emerging as an efficient way to reduce the carbon foot print of waste management while generating renewable energy. In general, gasification is a process where electromagnetic wave energy is used to heat biomass sufficiently to convert the bio-mass to ... En savoir plus

COMSOL Multiphysics® Software: Simplifying Workflow and Promoting Innovations in Nuclear Engineering at ORNL

P. K. Jain [1], J. D. Freels [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

At Oak Ridge National Laboratory (ORNL), COMSOL Multiphysics® software has become a preferred software for certain multiphysics applications in nuclear engineering. This presentation will highlight some of the ongoing activities in the following areas: (1) Highly enriched uranium (HEU) ... En savoir plus

Modelling of Reactive Non-Isothermal Mixture Flow and its Simulation in COMSOL Multiphysics® Software

V. Orava[1,2], O. Soucek[1], P. Cedula[2]
[1]Charles University in Prague, Prague, Czech Republic
[2]Zurich University of Applied Sciences, Winterthur, Switzerland

I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely ... En savoir plus

Complex Geometry Creation and Turbulent Conjugate Heat Transfer Modeling

I. Bodey[1], R. Arimilli[1], and J. Freels[2]
[1]Dept. of Mechanical, Aerospace and Biomedical Eng., The University of Tennessee, Knoxville, TN
[2]Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN

The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched ... En savoir plus

Mathematical Investigation and CFD Simulation of Monolith Reactors: Catalytic Combustion of Methane

M. Ghadrdan[1], and H. Mehdizadeh[2]
[1]Department of Chemical Engineering, Norwegian University of Science and Technology (NTNU), Trondheim, Norway
[2]Department of Chemical Engineering, Tarbiat Modares University, Tehran, Iran

Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic ...

CFD modeling of a commercial CVD system and simulation of a CVD deposition process

Oscar Alm¹, Micael Baudin¹
¹Seco Tools, Sweden

Seco Tools produces inserts for machining metals. Roughly half the number of inserts Seco Tools produces are coated by Chemical Vapour Deposition (CVD) which extends the inserts lifetime in machining operations significantly. More than 10 000 inserts are coated on trays in each CVD run. ... En savoir plus

Modeling of Transport and Reaction in a Catalytic Bed Using a Catalyst Particle Model

F. Allain, and A.G. Dixon
Worcester Polytechnic Institute, Worcester, MA, USA

A packed bed reactor consisting of spherical catalyst particles in a tube was simulated numerically. The steady-state pseudo-heterogeneous model consisted of a pseudo-continuum representation for the heat and mass transfer in the reactor tube. The reaction source terms were evaluated by ...

3D Dynamic Simulation of a Metal Hydride-Based Hydrogen Storage Tank

A. Freni, and F. Cipiti
CNR- Institute for Advanced Energy Technologies “Nicola Giordano”, Messina, Italy

In this paper, a 3D dynamic simulation for a portion of a metal hydride-based (LaNi5) hydrogen storage tank is presented. The model is based on heat and mass balances and considers coupled heat and mass transfer resistance through a non-uniform pressure and temperature sorbent bed. The ... En savoir plus
